PPP, PPPAPI: remove useless pppapi_set_auth function

Browse Source 
Setting PPP authentication most only be done when the PPP PCB is in the
dead phase (i.e. disconnected). This is safe to access the PPP PCB
members while the session is down, therefore providing a thread-safe
function of it is meaningless and it might even be misleading.

All our new ppp_set_* functions do not have their equivalent
pppapi_set_* functions and they are not going to have them. At least
we make ppp_set_auth consistent with all others ppp_set_*, so that it
doesn't look like special.
