Mark the current segment with SEGUSE_ACTIVE at mount time, rather than waiting 

for the first write.  If this is not done, the cleaner may try to clean the
current segment out from under the writer if the filesystem is mounted after
a crash (or any other time that the dirty:clean segment ration is high enough).
