block: Fix parameter checking in bdrv_co_copy_range_internal
src may be NULL if BDRV_REQ_ZERO_WRITE flag is set, in this case only
check dst and dst->bs. This bug was introduced when moving in the
request tracking code from bdrv_co_copy_range, in 37aec7d75eb.
This especially fixes the possible segfault when initializing src_bs
with a NULL src.
