block-backend: convert blk_co_pdiscard to int64_t bytes

We updated blk_do_pdiscard() and its wrapper blk_co_pdiscard(). Both
functions are updated so that the parameter type becomes wider, so all
callers should be OK with it.

Look at blk_do_pdiscard(): bytes is passed only to
blk_check_byte_request() and bdrv_co_pdiscard(), 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().
