n_gsm.c : Prevent adaption change while receiving datas

BZ: 40341

If ioctl GSMIOC_DISABLE_NET is issued on gsmtty associated to
network interface while IP traffic is icomming, in rare case
gsm_mux_rx_netchar can use variable (mux_net) that can no more
be valid. We add a mutex to prevent that. More generally we
prevent that adaption can change while incomming data are managed.
