[PATCH v3 1/2] gstreamer: allocator: gst_libcamera_allocator_new(): Recognize errors

[Barnabás Pőcze]

`FrameBufferAllocator::allocate()` might return a negative error code,
but currently this is handled the same way as success. So instead
of continuing, abort the construction of the allocator object.
