fix a buffer leak in outputmgrapplyortest()

Browse Source 
wlr_swapchain_acquire() returns a locked buffer and
wlr_output_state_set_buffer() takes its own lock, so every output enabled
through output management (wlr-randr, kanshi) leaked a buffer. Unlock it
once the state holds it, as wlr_output_swapchain_manager does.
