Set autosuspend delay for Fibocom LG850-GL

Browse Source 
It has been shown that the autosuspend delay for this device enacted
by modem manager will race with suspend and cause system suspend
failures.

This occurred in ChromiumOS on a chromebook, but there is no reason
it won't happen in regular notebooks with the same WWAN.  To avoid
the failure delay autosuspend to a frequency longer than the polling
rate used by modem manager.
