fs: Fix error checking for d_hash_and_lookup()

Browse Source 
[ Upstream commit 0d5a4f8f77 ]

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: eedf265aa0 ("devpts: Make each mount of devpts an independent filesystem.")
