Patch series "Cleanup patches of vmalloc".

Some cleanup patches found when reading vmalloc code.


This patch (of 5):

In function adjust_va_to_fit_type(), it checks all values of passed in fit
type, including NOTHING_FIT in the else branch.  In fact, it's unnecessary
to check NOTHING_FIT since the check has been done before
adjust_va_to_fit_type() is called in all call sites.  So clean it up.
