Subject: [PATCH] buffer: fix meta sequence number fallback on rpi

The global seqnum variable wasn't actually increased in
the fallback code path, leading to all buffers getting
a seqnum of 0. Which also made the unit test fail.

This affects platforms/toolchains that don't have
64-bit atomic ops such as when compiling for armv7 rpi.
