[igt-dev] [PATCH i-g-t] kms_dp_tiled_display: Fix the double free of drmConnector

[igt-dev] [PATCH i-g-t] kms_dp_tiled_display: Fix the double free of drmConnector

[Chris Wilson]

drmConnectorFree is called inside the loop and after. Not unsurprisingly
this leads to a use-after-free and memcorruption.
