[Why] This is consistent with Linux. [How] The definition is moved from <linux/shmem_fs.h> to <linux/pagemap.h> and the latter is included from the former. This is how it is done on Linux. Prototypes are also expanded with argument names. I got a build failure in the DRM 5.18 drivers because the compiler considered that the `pgoff_t` argument was there twice.
