flow: Move flow_count from context structure to a global

In general, the passt code is a bit haphazard about what's a true global
variable and what's in the quasi-global 'context structure'.  The
flow_count field is one such example: it's in the context structure,
although it's really part of the same data structure as flowtab[], which
is a genuine global.

Move flow_count to be a regular global to match.  For now it needs to be
public, rather than static, but we expect to be able to change that in
future.
