rilmodem: Don't parse error SMS reply

Don't parse an SMS reply if the error from
rild indicates FAILURE.  This could cause a
crash in parcel_r_int32() code (LP: #1260388).

rilmodem: Don't parse error SMS reply
gril: fix cancel_group/offline crash (LP: 1262340)

When the modem is set offline (for FlightMode), the
core ofono code will call remove() for the call-volume
and netreg drivers, which will result in the low-level
gril function ril_cancel_group() function being called.
This low-level function has a bug in its queue logic
which can result in commands which have already been
sent to rild being removed.  This causes problems when
a response is received, as the code asserts that the
command_queue length is >0 when an incoming response is
received.  This fix is based on a nemomobile ofono fix:

plugins: Re-factor ril power & SIM detection logic

Re-factor the plugin to only send a GET_SIM_STATUS
request once the radio has been confirmed to be on.
This closes a race condition during power on which
has caused intermittent erros with both SIM status
and SIM IO.
