Substituting 'uma_align_cache' by the appropriately named accessor
uma_get_cache_align_mask() made apparent that dma_get_cache_alignment()
was off by one, since it was defined to be the mask derived from the
alignment value.

(cherry picked from commit 2c7dd66d09a1b92a4698232996cded6e5315b3bd)
Create the uma_get_cache_align_mask() accessor and put it in a separate
private header so as to minimize namespace pollution in header/source
files that need only this function and not the whole 'uma.h' header.
Make sure the accessors have '_mask' as a suffix, so that callers are
aware that the real alignment is the power of two that is the mask plus
one. Rename the stem to something more explicit. Rename
uma_set_cache_align_mask()'s single parameter to 'mask'.
Hide 'uma_align_cache' to ensure that it cannot be set in any other way
then by a call to uma_set_cache_align_mask(), which will perform sanity
checks in a further commit. While here, rename it to
'uma_cache_align_mask'.
This is also in preparation for some further changes, such as improving
the sanity checks, eliminating internal resolving of UMA_ALIGN_CACHE and
changing the type of the 'uma_cache_align_mask' variable.

Commit 3f686532c9 tried to fix an issue with not properly starting
at the first page in the sg list to prevent a panic. This worked but
with the side effect of incrementing "s" during the final iteration
causing it to be NULL since the list had ended.
In cases non-DEBUG kernels this causes a panic with drm-5.15, since
"s" is NULL when we later pass it to sg_mark_end().
This change decouples the iteration sg from the return value so that
it is never incremented past the final page in the chain.

Commit 3e0856b63f updated
__sg_alloc_table_from_pages to use the same API as linux, but modified
the loop condition when going over the pages in a sg list. Part of the
change included moving the sg_next call out of the for loop and into the
body, which causes an off by one error when traversing the list. Since
sg_next is called before the loop body it will skip the first element
and read one past the last element.
This caused panics when running PRIME with nvidia-drm as the off-by-one
issue causes a NULL dereference.
