[SCSI] qla2xxx: Use bitmap to store loop_id's for fcports.

Browse Source 
Store used fcport loop_id's in a bitmap so that as opposed to looping through
all fcports to find the next free loop_id, new loop_id lookup can be just be
done via bitops.

[jejb: plus fix for incorrect LOOPID_MAP_SIZE from Andrew Vasquez]
