common: fix arm32 compile breakage.

It's obviously the incorrect type, while our CI didn't catch it, Nicholas did: ``` plugins/fetchinvoice.c:1362:30: error: conversion from 'long long unsigned int' to 'size_t' {aka 'unsigned int'} changes value from '18446744073709551615' to '4294967295' [-Werror=overflow] 1362 | || tlv_span(wire, 1001, UINT64_MAX, NULL) != 0) { ``` Reported-by: @NicholasDorier Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-Fixed: Build: arm32 compiler error in fetchinvoice, due to bad types on 32-bit platforms. Fixes: ElementsProject#5776
