[SCSI] fusion - removing target_id/bus_id from the VirtDevice structure
It makes no sense in keeping the target_id and bus_id in the VirtDevice structure, when it can be obtained from the VirtTarget structure. In addition, this patch fix's couple compilation bugs in mptfc.c when MPT_DEBUG_FC is enabled. This provided by Micheal Reed.
