qla3xxx: bugfix: Move link state machine into a worker thread

The link state machine requires access to some resources that
are shared with the iSCSI function on the chip.  (See iSCSI
driver at drivers/scsi/qla4xxx)  If the interface is being
up/downed at a rapid pace this driver may need to sleep
waiting to get access to the common resources. For this we
are moving the state machine to run as a work thread.
