dm space map metadata: remove unused variable in brb_pop()
Remove the unused struct block_op pointer that was inadvertantly introduced, via cut-and-paste of previous brb_op() code, as part of commit 50dd842ad. (Cc'ing stable@ because commit 50dd842ad did) Fixes: 50dd842ad ("dm space map metadata: fix ref counting bug when bootstrapping a new space map") Reported-by: David Binderman <dcb314@hotmail.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org
