drivers/net/hamradio: fix warning: format not a string literal and no ...

Impact: Use 'static const char[]' instead of 'static char[]' and while
being at it fix an issue in 'mkiss_init_driver', where in case of an
error the status code was not passed to printk.

Fix this warnings:
  drivers/net/hamradio/6pack.c: In function 'sixpack_init_driver':
  drivers/net/hamradio/6pack.c:802: warning: format not a string literal and no format arguments
