The driver here is simply reporting that the a command's timeout value
had been exceeded and the mid-layer began error-recovery with a request
to 'abort' the command.  The abort-request completed successfully:

	qla2xxx 0000:06:09.0: scsi(0:0:0): Abort command issued -- 1 fa6a73 2002.

I can't explain why the storage did not complete the request in the
allotted time.
