[Intel-gfx] [PATCH 4/6] tests/kms_flip: don't leak the CRTC

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

The kms_flip program calls kmstest_get_connector_config, which returns
a struct containing some allocated variables, including a pointer to
the CRTC. The problem is that we copy the values returned by this
structure to the test_output struct, but we ignore the CRTC pointer.
So free the CRTC pointer instead of leaking it.

Caught by Valgrind.
