huawei: fix online logic 

The recently introduced online support to huawei didn't work with my
Huawei E1552. The problem was that with command AT+CFUN=1;+CFUN=5
the modem didn't initialise the sim state properly.

To fix this I changed the logic so that CFUN=5 is called only after the sim
state has switched to a valid state. Now my Huawei E1552 works with connman
again.

PIN locked SIMs still won't work. The problem is that it takes some time for
the sim state to go to a valid state:

Sep 20 15:01:57 dell-m520 ofonod[12451]: Pcui:< \r\n+CPIN: READY\r\n\r\nOK\r\n
[...]
Sep 20 15:02:00 dell-m520 ofonod[12451]: huawei: invalid sim state in post online (0)
[...]
Sep 20 15:02:01 dell-m520 ofonod[12451]: Pcui:< \r\n^SIMST:1\r\n

I don't know why it takes so long to get a valid state.

There is also another issue, in "cold start" case the phonebook
initialisation fails:

Sep 20 14:34:24 dell-m520 ofonod[11939]: Pcui:> AT+CPBS=?\r
Sep 20 14:34:24 dell-m520 ofonod[11939]: Pcui:< \r\n+CME ERROR: SIM busy\r\n

But in "warm start" it seems to work:

Sep 20 14:38:59 dell-m520 ofonod[12091]: Pcui:> AT+CPBS=?\r
Sep 20 14:38:59 dell-m520 ofonod[12091]: Pcui:< \r\n+CPBS: ("SM","EN","ON")\r\n\r\nOK\r\n

I consider this as a minor issue and didn't investigate it at all.
