Because of the frequent channel change, it is possible that when we are
try to associate with channel 1 (authenticated but not associated).
Another channel change comes at this time, then the driver will issue
disassociate command to the firmware which will cause the fatal error.
It seems that the association/disassociation procedure should not be
interrupted.
The patch attached adds test on STATUS_ASSOCIATING | STATUS_DISASSOCIATING
in ipw_send_cmd(), when ensures that commands will not be sent to firmware
when we are in these two status.

captured, it will be dumped to the kernel log (if debug enabled) and
captured in memory to be retrieved via sysfs.
If an error has already been captured, subsequent errors will be
dropped.
The existing error can be cleared by writing to the error log entry.

We send SYSTEM_CONFIG command after the TGI_KEY command if hardware
encryption is enabled. It sometimes causes a firmware stall (firmware
doesn't respond to any request) and finally bungs up the Tx send queue.
The solution is to send SYSTEM_CONFIG command in the post association
stage from a workqueue.
