tty: n_gsm: increase malformed counter for malformed control frames
The malformed counter in gsm_mux is already increased in case of errors detected in gsm_queue() and gsm1_receive(). gsm_dlci_command() also detects a case for a malformed frame but does not increase the malformed counter yet. Fix this by also increasing the gsm_mux malformed counter in case of a malformed frame in gsm_dlci_command(). Note that the malformed counter is not yet exposed and only set internally.
