drm/i915: Fix rsvd2 mask when out-fence is returned
commit b1b13780ab06ef8c770dd9cbe31dac549a11630e upstream.
GENMASK_ULL wants the high bit of the mask first. The current value
cancels the in-fence when an out-fence is returned.
Fixes: fec0445caa273 ("drm/i915: Support explicit fencing for execbuf")
Testcase: igt/gem_exec_fence/keep-in-fence*
