block: Remove REQ_OP_ZONE_RESET plugging
REQ_OP_ZONE_RESET operations cannot be merged as these bios and requests do not have a size and are never sequential due to the zone start sector position required for their execution. As a result, there is no point in using a plug around blkdev_reset_zones() bio issuing loop. This patch removes this unnecessary plugging.
