Currently during fisa flow aggregation REO ID check is done to
make sure all the flow packets are received in same REO and to avoid
out of order reception. But if RX packet matches CCE rules REO ID
is selected based on CCE rules since they have higher priority.
In this case ignore RX packet for FISA aggregation and do not panic.

If many packets are queued into rx thread, processing
the packets can delay the vdev del event processing.
To fix this, check for vdev_del_event when processing

Currently we process and free the nbuf from
queue while holding a lock for the complete duration.
There might be a case when there are many packets pending
in the queue. This might cause the issue when we held the lock
and other process waits for lock.
So as part of the fix only perform the nbuf unlink inside the
lock and move the processing and free part outside the lock.
