which caused images to be loaded up to MmHighestUserAddress,
thus overwriting the shared user page.
This is now fixed by using MM_HIGHEST_VAD_ADDRESS as the margin instead.

Doing this is not only wrong because it acquires the same spinlock twice,
it also completely breaks the TLB flushing logic in MiMapPageInHyperSpace.
If the PTE with Offset 1 is still valid when a wrap-around to 0 happens,
the TLB flush on wrap-around will not clear the entry for this previous page.
After another loop around all hyperspace pages, page 1 is re-used but its
TLB entry has not been flushed, which may result into incorrect translation.
Experiment and MSDN tend to show that a dirty BCB is queued for lazy write.
This will do the job here!
Also, renamed CcRosMarkDirtyFile() which is more accurate, and added a new
function CcRosMarkDirtyVacb() which just takes a VACB as arg (expected locked)
and marks it dirty (using previous implementation). Make CcRosMarkDirtyFile()
use it.
