Is endianess support is properly implemented?

Is this cpu_to_le16() or what? Try avoid reinventing the wheel and use
what kernel provides you.

Also noticed lots of dev_info() spamming, please convert those to debug
messages.

And rx_usb_enabled is racy and it will not work if there are multiple
devices. Maybe move it to struct purelifi_usb or similar?
