Convert blk_pdiscard, blk_pwrite_compressed, blk_pwrite_zeroes. These are just wrappers for functions with int64_t argument, so allow passing int64_t as well. Parameter type becomes wider so all callers should be OK with it. Note that requests exceeding INT_MAX are still restricted by blk_check_byte_request(). Note also that we don't (and are not going to) convert blk_pwrite and blk_pread: these functions return number of bytes on success, so to update them, we should change return type to int64_t as well, which will lead to investigating and updating all callers which is too much. So, blk_pread and blk_pwrite remain unchanged.
