Commitc7640f8346was meant to fix a sign compare warning in clang because NLMSG_NEXT internally compares the length with nlmsghdr->nlmsg_len which is a u32. The problem is the NLMSG_NEXT can underflow an unsigned value, hence why it expects an int type to be passed in. To work around this we can instead pass a larger sized int64_t which the compiler allows since it can upgrade the unsigned nlmsghdr->nlmsg_len. There is no underflow risk with an int64_t either because the buffer used is much smaller than what can fit in an int64_t. Fixes:c7640f8346("monitor: fix integer comparison error (clang)")
