xfs: remove NULL pointer checks in xfs_mru_cache_insert
Remove the check for a NULL mru or mru->list in xfs_mru_cache_insert
as this API misused lead to a direct NULL pointer dereference on first
use and is not user triggerable. As a smatch run by Dan points out
with the recent cleanup it would otherwise try to free the object we
just determined to be NULL for this impossible to reach case.
