Re: [B.A.T.M.A.N.] [PATCH] batctl: change PATH_BUFF_LEN to maximal possible value

[Philipp Psurek <philipp.psurek@gmail.com>]

'snprintf' output in sys.c can be between 34 and 289 bytes and should
not write into a destination of size 200

snprintf(path_buff, PATH_BUFF_LEN, SYS_ROUTING_ALGO_FMT, iface_dir->d_name);
