Remove GuardedAsyncTask wrapper for call.cancel() (#48251)

Summary:
Pull Request resolved: #48251

The original comment mentioning square/okhttp#869 predates the [upgrade to okhttp3](6bbaff2), which resolved the issue via square/okhttp#1592.

Cancel calls should now be async and don't need to be guarded.  Removing this also fixes a discrepancy in NetworkingModule unit test verification.
