Add getter for quotaBytes

Since the counter part test is in internal branch only.
Change the member of OnSetLimit makes it fail to build on the
rvc+aosp branch.
Thus, add a getter for backward compatibility since the rvc test
does not recognize limitBytes.

This change also addresses some nullability confusions that are
not going to happen.

Test: m gts && atest \
          GtsNetworkStackHostTestCases:NetworkStatsHostTest#testNetworkStatsProvider
      on R & S codebase.
