Fix a very brief race which could cause page states to be corrupted.

Observed under heavy physio load from an 8-way parallel dump|restore
workload used in filesystem testing - manifested as intents being
scribbled over while the interlock was momentarily not held
in uvmpdpol_selectvictim.  I've attempted to apply the same fix to
clockpro, which looks like it needs it too, but clockpro was on fire
when I got there and I didn't put it out (still does not compile).

Fix an obvious typo which applied the wrong intent.  Still does not compile.

fix build with clockpro
