proc: Fix unbalanced hard link numbers
commit d66bb1607e2d8d384e53f3d93db5c18483c8c4f7 upstream.
proc_create_mount_point() forgot to increase the parent's nlink, and
it resulted in unbalanced hard link numbers, e.g. /proc/fs shows one
less than expected.
Fixes: eb6d38d5427b ("proc: Allow creating permanently empty directories...")
