Dmitry Chagin ccdf2cd423 linux(4): Check the socket before any others sanity checks 
Strictly speaking, this check is performed by the kern_recvit(), but in
the Linux emulation layer before calling the kernel we do other sanity
checks and conversions from Linux types to the native types. This changes
an order of the error returning that is critical for some buggy Linux
applications.

For recvmmsg() syscall this fixes a panic in case when the user-supplied
vlen value is 0, then error is not initialized and garbage passed to the
bsd_to_linux_errno().
