Hoppe, Mateusz e1eaf3ded0 Fix bug in VA sharing multithreaded scenario
- createGraphicsAllocationFromSharedHandle was not threadsafe,
instead of reusing BufferObject for a single handle when
multiple threads were creating memory objects from a single VASurface,
new BO could be created and placed in container with BOs for reuse.
This was leading to errors in ioctl calls.

- add lock for following set of operations:
 1. find BufferObject with a given handle in container
 2. create shared BO when not found
 3. add shared BO to container
 prevents creating multiple BOs for a single handle

- replace recursive mutex with regular mutex as mutex shouldn't
be locked recursively
