Code review comment for lp:~awe/phablet-extras/ofono-lp1204644

Note, to see the original bug in vivid detail, start ofonod in the foreground and set the debug flag to dump messages from gprs.c:

# ofonod -d */gprs.c -n -P atmodem

Now toggle the GPRS attached state either via the indicator toggle or via the ofono-script 'disable-gprs'.
