Fix pointer tests in error-handling paths
In the error-handling paths of i915_gem_do_execbuffer() and
intel_crtc_page_flip(), the local pointer-to-request variables
were expected to be either valid pointers or NULL. Since
2682708 drm/i915: simplify allocation of driver-internal requests
they could also be ERR_PTR() values, so the tests need to be
updated to accommodate this case.
