scsi: sd_zbc: Support disks with more than 2**32 logical blocks
This patch addresses the following Coverity report about the zno *
sdkp->zone_blocks expression:
CID 1475514 (#1 of 1): Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
overflow_before_widen: Potentially overflowing expression zno *
sdkp->zone_blocks with type unsigned int (32 bits, unsigned) is evaluated
using 32-bit arithmetic, and then used in a context that expects an
expression of type sector_t (64 bits, unsigned).
