fs: Fix error checking for d_hash_and_lookup()
[ Upstream commit 0d5a4f8f775ff990142cdc810a84eae078589d27 ]
The d_hash_and_lookup() function returns error pointers or NULL.
Most incorrect error checks were fixed, but the one in int path_pts()
was forgotten.
Fixes: eedf265aa003 ("devpts: Make each mount of devpts an independent filesystem.")
