Subject: drm/i915/gvt: Correct ADDR_4K/2M/1G_MASK definition

From: Xiong Zhang <xiong.y.zhang@intel.com>

commit b721b65af4eb46df6a1d9e34b14003225e403565 upstream.

For ADDR_4K_MASK, bit[45..12] should be 1, all other bits
should be 0. The current definition wrongly set bit[46] as 1
also. This path fixes this.

v2: Add commit message, fixes and cc stable.(Zhenyu)
