Fix compile warning in get_addr_1

A recent cleanup causes a compile warning on Debian jessie:

    CC       utils.o
utils.c: In function ‘get_addr_1’:
utils.c:486:21: warning: passing argument 1 of ‘ll_addr_a2n’ from incompatible pointer type
   len = ll_addr_a2n(&addr->data, sizeof(addr->data), name);
                     ^
In file included from utils.c:34:0:
../include/rt_names.h:27:5: note: expected ‘char *’ but argument is of type ‘__u32 (*)[8]’
 int ll_addr_a2n(char *lladdr, int len, const char *arg);
     ^

Revert the removal of the typecast
