block/mirror: fix -Werror=maybe-uninitialized false-positive
../block/mirror.c:404:5: error: ‘ret’ may be used uninitialized [-Werror=maybe-uninitialized]

../block/mirror.c:578:12: error: ‘ret’ may be used uninitialized [-Werror=maybe-uninitialized]

which is int and is passed as an int argument to mirror_read_complete()"
