scsi: Revert "scsi: core: Do not increase scsi_device's iorequest_cnt if dispatch failed"
commit 6ca9818d1624e136a76ae8faedb6b6c95ca66903 upstream.
The "atomic_inc(&cmd->device->iorequest_cnt)" in scsi_queue_rq() would
cause kernel panic because cmd->device may be freed after returning from
scsi_dispatch_cmd().
This reverts commit cfee29ffb45b1c9798011b19d454637d1b0fe87d.
