BRT: Check bv_mos_entries in brt_entry_lookup()
When vdev first sees some block cloning, there is a window when
brt_maybe_exists() might already return true since something was
cloned, but bv_mos_entries is still 0 since BRT ZAP was not yet
created. In such case we should not try to look into the ZAP
and dereference NULL bv_mos_entries_dnode.
