fixed lockref check in lock_parent()
lockref.count is unsigned int on vz7 kernels
so backport of upstream commit c2338f2dc7c1e9
"lock_parent: don't step on stale->d_parent of all-but-freed one"
requires correction.
Fixes vz7 commit "ms/lock_parent() needs to recheck if dentry got
__dentry_kill'ed under it"
