staging: wilc1000: Increase the size of wid_list array
[ Upstream commit a4338ed2e1cf724563956ec5f91deeaabfedbe23 ]
Increase by one the size of wid_list array as index variable can reach a
value of 5. If this happens, an out-of-bounds access is performed.
Also, use a #define instead of a hard-coded literal for the new array
size.
