i965/blorp: Fix hiz ops on MSAA surfaces
Two things were broken here:
- The depth/stencil surface dimensions were broken for MSAA.
- Sample count was programmed incorrectly.
Result was the depth resolve didn't work correctly on MSAA surfaces, and
so sampling the surface later produced garbage.
Fixes the new piglit test arb_texture_multisample-sample-depth, and
various artifacts in 'tesseract' with msaa=4 glineardepth=0.
Fixes freedesktop bug #76396.
Not observed any piglit regressions on Haswell.
v2: Just set brw_hiz_op_params::dst.num_samples rather than adding a
helper function (Ken).

v3: moved the alignment needed for hiz+msaa to brw_blorp.cpp, as
suggested by Chad Versace (Alejandro Piñeiro on behalf of Chris
Forbes)
