Subject: [PATCH v6 3/9] tty: n_gsm: remove unneeded initialization of ret in gsm_dlci_config

From: Daniel Starke <daniel.starke@...mens.com>

The variable 'ret' is not used before assignment from gsm_activate_mux().
Still it gets initialized to zero at declaration.

Fix this as remarked in the link below by moving the declaration to the
first assignment.
