Subject: mm/vmalloc: remove the unnecessary type check

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.
