scsi: sd_zbc: Fix variable type and bogus comment

Fix the description of sd_zbc_check_zone_size() to correctly explain that
the returned value is a number of device blocks, not bytes.  Additionally,
the 32 bits "ret" variable used in this function may truncate the 64 bits
zone_blocks variable value upon return. To fix this, change "ret" type to
s64.
