Andre Puschmann 7ac0c3a8e0 epc,s1ap: don't log error when receiving UE capability info from eNB
this fixes a warning that we had in the epc.log because we don't
explicitly handle the UE capability info message received over S1AP
from the eNB.

Since we have a strict no-error policy in many PR tests, we can't log
an error here.
