Subject: drm/i915: Fix rsvd2 mask when out-fence is returned

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>

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*
