ip{6, }tunnel: Avoid copying user-supplied interface name around
In both files' parse_args() functions as well as in iptunnel's do_prl()
and do_6rd() functions, a user-supplied 'dev' parameter is uselessly
copied into a temporary buffer before passing it to ll_name_to_index()
or copying into a struct ifreq. Avoid this by just caching the argv
pointer value until the later lookup/strcpy.
