dlm: use rwlock for rsb hash table
The conversion to rhashtable introduced a hash table lock per lockspace, in place of per bucket locks. To make this more scalable, switch to using a rwlock for hash table access. The common case fast path uses it as a read lock. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>
