scsi: scsi_debug: Zero clear zones at reset write pointer

When a reset is requested the position of the write pointer is updated but
the data in the corresponding zone is not cleared. Instead scsi_debug
returns any data written before the write pointer was reset. This is an
error and prevents using scsi_debug for stale page cache testing of the
BLKRESETZONE ioctl.

Zero written data in the zone when resetting the write pointer.
