btrfs-progs: fix show super unknown flag output 

coverity pointed out that unknown flag printing in show super had some
dead code.  It turns out that first was reset when the first flag was
tested, not when it was output.  We only want to clear it if the first
matching bit is output.  If there are no matching bits then we'll want
to output the unknown flag first.
