scsi: qla2xxx: Add SLER and PI control support 

BIT_13 of extended FW attribute informs about NVMe-2 support.  Set BIT_15
of special feature control block for enabling SLER in FW.  Set bit 8 (SLER
supported) to 1 for the service parameter information when sending NVMe
PRLI request.  Set BIT_14 of special feature control block for enabling PI
Control in FW.  Driver should set bit 9 (PI Control supported) to 1 for the
service parameter information when sending NVMe PRLI request.  Set BIT_13
for NVMe Async events.
