MFC r280757: Remove request sorting from GEOM_MIRROR and GEOM_RAID.
When CPU is not busy, those queues are typically empty. When CPU is busy,
then one more extra sorting is the last thing it needs. If specific device
(HDD) really needs sorting, then it will be done later by CAM.
This supposed to fix livelock reported for mirror of two SSDs, when UFS
fires zillion of BIO_DELETE requests, that totally blocks I/O subsystem by
pointless sorting of requests and responses under single mutex lock.

When an mbuf allocation fails in the receive path, the mbuf containing the received packet is not sent to the host network stack and is reused again on the receive ring. Remaining received packets in the ring are not processed in that invocation of bxe_rxeof() and defered to the task thread
When catopen(3) returns an error, it caches the result of that error from
r202992. The refcount on the cache entry is not initialized, so any attempt
to clean the cache will skip over this item since it likely has a >0 value.
