dm space map metadata: remove unused variable in brb_pop()

commit 51216778 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 50dd842a.

(Cc'ing stable@ because commit 50dd842a did)

Fixes: 50dd842a ("dm space map metadata: fix ref counting bug when bootstrapping a new space map")
