[ Upstream commit 26f9ce53817a8fd84b69a73473a7de852a24c897 ]
Aborting commands that have already been sent to the firmware can cause BUG in qlt_free_cmd(): BUG_ON(cmd->sg_mapped)
For instance:
- Command passes rdx_to_xfer state, maps sgl, sends to the firmware
- Reset occurs, qla2xxx performs ISP error recovery, aborts the command
- Target stack calls qlt_abort_cmd() and then qlt_free_cmd()
- BUG_ON(cmd->sg_mapped) in qlt_free_cmd() occurs because sgl was not unmapped
Thus, unmap sgl in qlt_abort_cmd() for commands with the aborted flag set.

[ Upstream commit 5e469ed9764d4722c59562da13120bd2dc6834c5 ]
When the QoS ack policy was set to non explicit / psmp ack, frames are treated as not being part of a BA session, which causes extra latency on reordering. Fix this by only bypassing reordering for packets with no-ack policy
