Subject: Fix header_interval minimum value
X-Git-Tag: fio-1.17~29

Fix header_interval minimum value

It doesn't make sense to have a value of header size or less, since
then there's no room for actual data. Fio even crashes with a value
less than the header size.

Lets just make the minimum twice the header size, seems reasonable...
