dlm: use RSB_HASHED to avoid lookup twice
Since commit 01fdeca1cc2d ("dlm: use rcu to avoid an extra rsb struct
lookup") _dlm_master_lookup() is called under rcu lock that prevents
that the rsb structure is being freed. There was a missing change to
avoid an additional lookup and just check that the rsb is still part of
the ls_rsbtbl structure. This patch is doing such check instead of
lookup the rsb structure again.
