dm space map metadata: fix missing store of apply_bops() return value
commit ae148243d3f0816b37477106c05a2ec7d5f32614 upstream.
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.
Fixes: 6096d91af0b6 ("dm space map metadata: fix occasional leak of a metadata block on resize")
