scsi: lpfc: Restrict support for 32 byte CDBs to specific HBAs

Browse source

An older generation of HBAs are failing FCP discovery due to usage of an
outdated field in FCP command WQEs.

Fix by checking the SLI Interface Type register for applicable support of
32 Byte CDB commands, and restore a setting for a WQE path using normal 16
byte CDBs.
