scsi: qla2xxx: SAN congestion management implementation
* Firmware Initialization with SCM enabled based on NVRAM setting and
firmware support (About Firmware).
* Enable PUREX and add support for fabric performance impact
notification (FPIN) handling.
* Allocate a default PUREX item for each vha to handle memory allocation
failures in ISR.
