Currently, the err variable in fib_check_nh_v4_gw may be used
uninitialized leading to the warning below:
fib_semantics.c: In function ‘fib_check_nh_v4_gw’:
fib_semantics.c:1023:12: warning: ‘err’ may be used
uninitialised in this function [-Wmaybe-uninitialized]
if (!tbl || err) {
^~
Initialize err to 0 to fix the warning.
