i915, debugfs: Fix uninitialized warning
gcc complains that: drivers/gpu/drm/i915/i915_debugfs.c: In function ‘display_crc_ctl_write’: drivers/gpu/drm/i915/i915_debugfs.c:2393:2: warning: ‘val’ may be used uninitialized in this function [-Wuninitialized] drivers/gpu/drm/i915/i915_debugfs.c:2350:6: note: ‘val’ was declared here but it can't see that we're going to use val only in the success case. So shut it up.
