This patch converts lpfc to use DID_TRANSPORT_DISRUPTED. I did not
do the queuecommand conversion of DID_BUS_BUSY because the
SCSI_MLQUEUE_TARGET_BUSY patches convert that.
Patch was tested with a direct connection by unplugging cables.
I did not hit the port of fabric busy paths, but saw that a distro
lpfc driver converted that bus busy to DID_TRANSPORT_DISRUPTED.
Also it looks like qla2xxx blocks the rport for that case.
