If an unsolicited ABTS was received, the driver looks up the
exchange it references. It it does various searches looking for
the exchange context. When one is eventually matched and it is
associated with an XRI context, the driver sends an ABORT WQE
to terminate the exchange. Current code looks at whether the
transport had taken action on the XRI yet or not  (no action if
set to LPFC_NVMET_STE_RCV; action if non-LPFC_NVMET_STE_RCV).
Based on action or not one of two (sol vs unsol) issue abort
routines are called. The unsol version cheats and transmits a
sequence containing an ABTS with no interaction with the adapter.
The sol version issues an Abort WQE and lets the adapter manage
whether the ABTS is sent to not.

The issue is the unsol version is sending ABTS unconditionally
for the exchange that received the ABTS. It's unnecessary.

Remove the conditional and just call the adapter command-based
routine to let the adapter manage the ABTS.
