ublk: zoned: support REQ_OP_ZONE_RESET_ALL
There isn't any reason to not support REQ_OP_ZONE_RESET_ALL given everything
is actually handled in userspace, not mention it is pretty easy to support
RESET_ALL.
So enable REQ_OP_ZONE_RESET_ALL and let userspace handle it.
Verified by 'tools/zbc_reset_zone -all /dev/ublkb0' in libzbc[1] with
libublk-rs based ublk-zoned target prototype[2], follows command line
for creating ublk-zoned:
cargo run --example zoned -- add -1 1024 # add $dev_id $DEV_SIZE
