dear linuxfoundation:
I'm very sorry has some problems in before's submit. now i divided the problems in two patches.
patch1:move ZTE CDMA device pid from zte_ev.c back to option.c.
reason: the pid of 0xfffe device can't re-connect succusfull when driven by zte_ev, but work fine when driven by option.
move the pid 0xfffe from zte_ev.c back to option.c.

patch2: Modify the parameter from 0x0003 to 0x0000. you must submit patch1 at first.
Reason:In the USB serial protocol, if set the control state (SET_CONTROL_LINE_STATE(22h)) and the parameter of RTS must be 0x0000
that make the carrier signal invalid state when close network. otherwise can't disconnect the network.
