[PATCH 11/19] migration/block: fix -Werror=maybe-uninitialized false-positive

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

../migration/block.c:966:16: error: ‘ret’ may be used uninitialized 
[-Werror=maybe-uninitialized]

Given that "cluster_size" must be <= BLK_MIG_BLOCK_SIZE, the previous
loop is entered at least once, so 'ret' is assigned a value in all conditions.
