intel: initialize bufmgr.bo_mrb_exec unconditionally

Browse source 
If bufmgr.bo_mrb_exec is not set, drm_intel_bo_mrb_exec returns ENODEV
even though drm_intel_gem_bo_mrb_exec2 will work fine for the RENDER ring.
Fixes xf86-video-intel after commit 'add BLT ring support' (5bed685f76)
with kernels without BSD or BLT ring support (2.6.34 and before).
