remove pointless va_copy to avoid cleanup dance
A va_copy call needs to be closed in all branches with va_end, so these functions would need to be reworked slightly, but we don't actually need to copy the va_list as we don't work on it, we just push it forward, so dropping the copy and everyone is happy. Reported-By: cppcheck Gbp-Dch: Ignore
