scsi: qla2xxx: Add logic to detect ABTS hang and response completion
ABTS error completion can trigger an exchange cleanup from the driver and
another ABTS response will be generated. This retry of ABTS response can
cause loop between driver trying to send ABTS and firmware returning error.
This patch fixes this issue by adding logic to check for unresolved exchanges
and clean up before ABTS is retried. This patch also addes the fix to use the
same qpair as the ABTS completion for the terminatation of exchange as well as
retry of ABTS response.
