clear errno after successful call

Browse source 
When preparing the debian stable backport, I am seeing a call to statvfs()
succeed, but also set errno to 2 (ENOENT). Not sure why this happens;
I am in a schroot when it does happen, or perhaps stable's libc is a little
broken and sets errno incorrectly. Anyway, it should be perfectly fine to
clear errno after the successful call, rather than before it.
