drm_hwcomposer: On error, free active composition

If we drop a frame while compositing, free the active composition.

Assume a frame pipeline of A->B->A. If we drop frame B, it will become
the active composition, which means the fences for A will not be released,
causing us to block A on A --> DEADLOCK.

BUG=b/29122961
TEST=Tested on smaug, no longer hangs
