Remove suspend-related code from GobiModem.

cromo no longer registers for suspend delays, since the
corresponding functionality has been moved into shill.  This
change removes code from GobiModem that attempts to avoid
connecting when the system is about to suspend -- this code
looks like it's never triggered due to cromo's suspend-delay
code being disabled.

BUG=chromium-os:30587,chromium-os:36980
TEST=manual: modem still works after suspending and resuming
