gprs: Let gprs_context interface be settable once
This patch allows a driver to set the interface only once, instead of at
every context activation. The previous way was originally designed for
PPP and RAW_IP based contexts which would have a (potentially)
differently named interface after each context activation due to use of
TUN/TAP. This also worked for static high-speed interface setups as
well, since these usually had a single interface only.
For devices that support multiple high-speed interfaces it would be
advantageous to have each gprs_context get an interface assignment right
in the modem driver and skip having to setup the interface on every
activation.
