Subject: [PATCH] osd-thumbnail: fix failed to get client texture

Use wlr_client_buffer->texture directly instead of wlr_texture_from_buffer.
All buffers in content_tree are wlr_client_buffer.

wlr_texture_from_buffer calls client_buffer_begin_data_ptr_access which
fails when client_buffer->source == NULL (client released buffer early,
e.g. wl_shm foot-terminal).
