Sort out what to do about emberGetCurrentNetwork

[bzbarsky-apple]

Problem

In the initial landing in #1609, we commented out calls to emberGetCurrentNetwork in util.c and attribute-storage.c.

Proposed Solution

We should figure out what, if anything, this maps to in the context of CHIP and either uncomment the calls and make them work or remove them.

This is likely related to https://github.com/project-chip/connectedhomeip/issues/1934
