[SCSI] qla2xxx: Add qla2x00_free_fcports() function

This function was added to encapsulate freeing the memory for all the fcports
associated with a particular vha.  Also added a call to qla2x00_free_fcports()
to qla2x00_free_device() to free the memory for all the fcports associated with
a vha during device removal.
