This patch makes the health check procedure aware of PCI channel issues, and in case of error recovery process, the function aac_adapter_check_health() returns -1 and let the recovery process to complete successfully. This patch was tested on upstream kernel v4.11-rc5 in PowerPC ppc64le architecture with adapter 9005:028d (VID:DID) - the error recovery procedure was able to recover fine.
