5.15-stable review patch. If anyone has any objections, please let me know.

commit 12a1c9353c47c0fb3464eba2d78cdf649dee1cf7 upstream.
REQ_OP_ZONE_RESET_ALL is a zone management request. Fix op_is_zone_mgmt() to return true for that operation, like it already does for REQ_OP_ZONE_RESET.
While no problems were reported without this fix, this change allows strengthening checks in various block device drivers (scsi sd, virtioblk, DM) where op_is_zone_mgmt() is used to verify that a zone management command is not being issued to a regular block device.
