msm8974-common: libril: Get off my back

Browse Source 
* Checking numInts and numStrings for strict equality when
  we're not looping is dumb, because Samsung is notorious
  for sending extra information in their RIL
* Check if there's *enough* data rather than the *exact amount*
  to fix a bunch of invalid response errors
