Hoppe, Mateusz 5be98e2e0f Fix VA sharing scenario ...

- make createGraphicsAllocationFromSharedHandle and
freeGraphicsMemory more threadsafe - there was race condition
where one thread called PRIME_FD_TO_HANDLE ioctl when the other just
closed the last handle with GEM_CLOSE ioctl. This led to situation
where newly acquired handle from PRIME_FD_TO_HANDLE was already invalid
and used in exec.

- adding mutex for the time of accessing shared handles container
 and ioctls (GEM_CLOSE and PRIME_FD_TO_HANDLE) resolves racing problem
