fs: Remove unlikely() from fput_light()

In fput_light(), there's an unlikely(fput_needed), which running on
my normal desktop doing firefox, xchat, evolution and part of my distcc farm,
and running the annotate branch profiler shows that the unlikely is not
very unlikely.

Which gives 1032903812 times it was correct and 6203351846 times it was
incorrect, or 85% incorrect.
