scsi: sd_zbc: Remove set but not used variable 'buflen'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/sd_zbc.c: In function 'sd_zbc_check_zones':
drivers/scsi/sd_zbc.c:341:9: warning:
 variable 'buflen' set but not used [-Wunused-but-set-variable]

It is not used since commit d9dd73087a ("block: Enhance
blk_revalidate_disk_zones()")
