scsi: fnic: Decode firmware role configuration

Browse source

Add FNIC_ROLE_CONFIG_MASK and use it to decode firmware role bits when
reading vNIC configuration and probing the PCI device.

Accept FCP and NVMe initiator roles, report FC target and FC-NVMe target
roles explicitly as unsupported, and keep truly undefined role settings on
the existing FC initiator default path.

Log the configured role flags and expose role names for trace output.
