qla2x00t-32gbit: NVME|FCP prefer flag not being honored

Changing of [FCP|NVME] prefer flag in flash has no effect on driver. For
device that supports both FCP + NVMe over the same connection, driver
continues to connect to this device using the previous successful login
mode.

On completion of flash update, adapter will be reset. Driver will
reset the prefer flag based on setting from flash.
