net: fix rtnh_ok()
[ Upstream commit b1993a2de12c9e75c35729e2ffbc3a92d50c0d31 ]
syzbot reported :
BUG: KMSAN: uninit-value in rtnh_ok include/net/nexthop.h:11 [inline]
BUG: KMSAN: uninit-value in fib_count_nexthops net/ipv4/fib_semantics.c:469 [inline]
BUG: KMSAN: uninit-value in fib_create_info+0x554/0x8d20 net/ipv4/fib_semantics.c:1091
@remaining is an integer, coming from user space.
If it is negative we want rtnh_ok() to return false.
Fixes: 4e902c57417c ("[IPv4]: FIB configuration using struct fib_config")
