layers: allow one thread multiple uses of object

A single call in a thread may use an object more than once.
This first appeared with vkCmdExecuteCommands and buffer pools.
That is not distinguishable from recursive vulkan calls.
The error that this was looking for only happens if calling vulkan
while within another vulkan call.  Such calls from signal handlers
or callbacks should be very rare errors.  So just allow one thread
to have multiple uses of an object and keep accurate counters.
