Subject: [PATCH] Remove unused method from MatchAllNetworkSpecifier

checkNotMatchAllNetworkSpecifier is a hidden method inside
MatchAllNetworkSpecifier, and the callers have implemented
the logic by themselves to prevent calling hidden method.
Remove it because there is no one using it.

Test: atest FrameworksNetTests
