There is an issue when network operators return "allowed" flag no matter
which SIM card you are using currently. In that case, when user tries to
manually connect to such networks, it takes too long to have 2 (by
default) retries until device will get back to its home network.
So the solution is not to set additional retries to the
RIL_REQUEST_SET_NETWORK_SELECTION_MANUAL request, as it has been done
