Check sanity the MNC length value from the SIM card

In case the SIM entry is wrong or we force reading of it, nasty things
like this can happen:

ofonod[12456]: Control:> AT+CRSM=176,28589,0,0,4\r
ofonod[12456]: Control:< +CRSM: 144,0,"00FFFF"\r\n\r\nOK\r\n
*** buffer overflow detected ***: ./src/ofonod terminated
