wined3d: Improve detection of device palette change.

[Alexander Dorofeyev]

Hi.

I just put it nearby other somewhat related calls. This code doesn't really need 
ENTER_GL/LEAVE_GL, but there's a bigger problem that this ENTER_GL/LEAVE_GL in 
PreLoad is around other routines too that mostly don't need it and leads to 
ActivateContext being called inside it etc. I've already sent a patch to remove 
ENTER_GL/LEAVE_GL in PreLoad, but it wasn't fully ok. I plan to fix and resend 
the latter patch after issues are taken care of (a bit of lack of consistency 
with holding / not-holding the lock in LoadLocation and its helper routines).
