qmi_wwan: unconditionally reject 2 ep interfaces
We have been using the fact that the QMI and DIAG functions usually are the only ones with class/subclass/protocol being ff/ff/ff on Quectel modems. This has allowed us to match the QMI function without knowing the exact interface number, which can vary depending on firmware configuration. The ability to silently reject the DIAG function, which is usually handled by the option driver, is important for this method to work. This is done based on the knowledge that it has exactly 2 bulk endpoints. QMI function control interfaces will have either 3 or 1 endpoint. This rule is universal so the quirk condition can be removed. The fixed layouts known from the Gobi1k and Gobi2k modems have been gradually replaced by more dynamic layouts, and many vendors now use configurable layouts without changing device IDs. Renaming the class/subclass/protocol matching macro makes it more obvious that this is now not Quectel specific anymore.
