Gracefully handle revoked ACCESS_NETWORK_STATE permission.

This permission has normal access right and can't be revoked by the user.
However, an app can choose to revoke it when using ExoPlayer, e.g. if
no network is required and the app doesn't want to list this permission.

Support this use case by gracefully catching the exception in the relevant
places.
