scsi: lpfc: Fix io lost on host resets

Browse source

If the driver undergoes repeated host resets it starts losing exchange
structures and eventually returns SCSI_MLQUEUE_HOST_BUSY and does not
recover. The offline path is not reclaiming the outstanding ios on the fcp
pring txcmplq before calling lpfc_destroy_multixripool, which causes the
txmcplq to be reinit and the resources lost.

Flush the fcp rings before destroying the multixripools.
