gfs2: Fix missed wakeups in find_insert_glock
Mark Syms has reported seeing tasks that are stuck waiting in
find_insert_glock. It turns out that struct lm_lockname contains four padding
bytes on 64-bit architectures that function glock_waitqueue doesn't skip when
hashing the glock name. As a result, we can end up waking up the wrong
waitqueue, and the waiting tasks may be stuck forever.
Fix that by using ht_parms.key_len instead of sizeof(struct lm_lockname) for
the key length.
