compat_ioctl: ppp: move simple commands into ppp_generic.c
All ppp commands that are not already handled in ppp_compat_ioctl()
are compatible, so they can now handled by calling the native
ppp_ioctl() directly.
Without CONFIG_BLOCK, the generic compat_ioctl table is now empty,
so add a check to avoid a build failure in the looking function for
that configuration.
