Bug Description

[Impact]
There is a rate of crash when doing suspend and resume test when using WWAN with PIN set on SIM.

[Test Case]
With WWAN enabled, and have PIN set on SIM, doing stress test of suspend & resume, some crash may be observed in network-manager.

Also the e.u.c should no longer receive the same crash reports after installing the update.

[Regression Potential]
The fix is checking a pointer before loop traverse which should be fair safe.
