dm space map metadata: remove unused variable in brb_pop()
commit 512167788a6fe9481a33a3cce5f80b684631a1bb upstream.
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")
