n_gsm: fix the wrong FCS handling
FCS could be GSM0_SOF, so will break state machine... [This byte isn't quoted in any way so a SOF here doesn't imply an error occurred.] Signed-off-by: Alek Du <alek.du@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Cc: stable <stable@kernel.org> [3.0] [Trivial but best backported once its in 3.1rc I think] Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
