[PATCH i-g-t 2/2] tests/intel/kms_sharpness_filter: Restore CRTC binding

[Swati Sharma <swati2.sharma@intel.com>]

After each tap iteration, cleanup() calls igt_display_reset()
which clears the output's pending_crtc binding. Subsequent tap
iterations (e.g. tap-5 after tap-3) then fail with -EIO during
pipe CRC collection because the output has no CRTC assigned.

Fix by conditionally restoring the CRTC binding via
igt_output_set_crtc() when pending_crtc is NULL.
