Since there is no getparam for hardware context support, Mesa always
tries to obtain a context by calling drm_intel_gem_context_create and
NULL-checking the result. On an older kernel without context support,
this caused libdrm to print an unwanted message to stderr:
DRM_IOCTL_I915_GEM_CONTEXT_CREATE failed: Invalid argument
In fact, this caused every Piglit test to fail with a "warn" status due
to the unrecognized error message.
Simply delete the message. It's OK for context creation to fail.
