[PATCH] xsm/flask: Fix XSM support for HVMOP_track_dirty_vram
This patch is intended for Xen 4.1 branch.
The XSM check for HVMOP_track_dirty_vram is done with a call to xsm_hvm_param,
therefore the switch handling that case should be located in flask_hvm_param
and not in flask_hvmcontext.
This was fixed upstream by the two following patches :
* 875756ca34fabc7243c4a682ffd7008710a907e2 (add case in flask_hvm_param)
* 652f94327383c5517b709f0a3e4b970216b3d375 (remove case from flask_hvmcontext)
