kernfs: fix potential NULL dereference in __kernfs_remove
When lockdep is enabled, lockdep_assert_held_write would
cause potential NULL pointer dereference.
Fix the following smatch warnings:
fs/kernfs/dir.c:1353 __kernfs_remove() warn: variable dereferenced before check 'kn' (see line 1346)
Fixes: 393c3714081a ("kernfs: switch global kernfs_rwsem lock to per-fs lock")
