dm space map metadata: fix missing store of apply_bops() return value
In commit 6096d91af0b6 ("dm space map metadata: fix occasional leak of a metadata block on resize"), we refactor the commit logic to a new function 'apply_bops'. But when that logic was replaced in out() the return value was not stored. This may lead out() returning a wrong value to the caller.
