tmpfs: fix uninitialized return value in shmem_link
[ Upstream commit 29b00e609960ae0fcff382f4c7079dd0874a5311 ]
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: 1062af920c07 ("tmpfs: fix link accounting when a tmpfile is linked in")
