Daniel Starke cec9c56c93 tty: n_gsm: fix tty registration before control channel open
commit 01aecd917114577c423f07cec0d186ad007d76fc upstream.

The current implementation registers/deregisters the user ttys at mux
attach/detach. That means that the user devices are available before any
control channel is open. However, user channel initialization requires an
open control channel. Furthermore, the user is not informed if the mux
restarts due to configuration changes.
Put the registration/deregistration procedure into separate function to
improve readability.
Move registration to mux activation and deregistration to mux cleanup to
keep the user devices only open as long as a control channel exists. The
user will be informed via the device driver if the mux was reconfigured in
a way that required a mux re-activation.
This makes it necessary to add T2 initialization to gsmld_open() for the
ldisc open code path (not the reconfiguration code path) to avoid deletion
of an uninitialized T2 at mux cleanup.

Fixes: d50f6dcaf22a ("tty: n_gsm: expose gsmtty device nodes at ldisc open time")
