Thanks for working on the rstp code!

This patch causes a huge number of build failures with Clang, like this:

    In file included from ../lib/rstp.c:32:
    ../lib/rstp.h:135:18: error: use of undeclared identifier 'rstp_mutex'
    ../include/openvswitch/compiler.h:136:57: note: expanded from macro 
'OVS_EXCLUDED'

I think that's the only reason that rstp_mutex is global.
