No significant advantage, and just eye-balled this redundant work.
Here's updated version. Only check compilation this time.
----
Simplify paging_invlpg when flush is not required.
Add paging_invlpg_noflush, when flush check is not required.
It's wasteful to always validate shadow linear mapping if
caller doesn't check return value at all.
