In the mknod(), mkfifo(), link(), symlink() and undelete() syscalls,
use vrele() instead of vput() on the parent directory vnode returned
by namei() in the case where it is equal to the target vnode. This
handles namei()'s somewhat strange (but documented) behaviour of
not locking either vnode when the two vnodes are equal and LOCKPARENT
but not LOCKLEAF is specified.

Note that since a vnode double-unlock is not currently fatal, these
coding errors were effectively harmless.
