block-backend: convert blk_co_copy_range to int64_t bytes
Function is updated so that parameter type becomes wider, so all
callers should be OK with it.
Look at blk_co_copy_range() itself: bytes is passed only to
blk_check_byte_request() and bdrv_co_copy_range(), which already have
int64_t bytes parameter, so we are OK.
Note that requests exceeding INT_MAX are still restricted by
blk_check_byte_request().
