tmpfs: fix uninitialized return value in shmem_link

When we made the shmem_reserve_inode call in shmem_link conditional, we
forgot to update the declaration for ret so that it always has a known
value.  Dan Carpenter pointed out this deficiency in the original patch.

Fixes: 1062af92 ("tmpfs: fix link accounting when a tmpfile is linked in")
