scsi: sd_zbc: Fix sd_zbc_read_zoned_characteristics()
commit 4a109032e3941413d8a029f619543fc5aec1d26d upstream.
The three values starting at byte 8 of the Zoned Block Device
Characteristics VPD page B6h are 32 bits values, not 64bits. So use
get_unaligned_be32() to retrieve the values and not get_unaligned_be64()
Fixes: 89d947561077 ("sd: Implement support for ZBC devices")
