miniobject: lock: check share refs does not go out of bounds

I am proposing this patch in order to detect if the counter used for
GST_LOCK_FLAG_EXCLUSIVE mode is going out of bounds.

It seems that it can have up to 32767 (0x7FFF0000 / 0x10000) refs.
Could this be not enough for some use cases and then provoke the warning in
gst_mini_object_unlock ?

I am not sure if the use cases exposed here are dealing with that, but this
check is harmless and useful if the counter is aiming to go out of bounds.
