Mark Bloch e945130b52 IB/core: Protect against concurrent access to hardware stats
Currently access to hardware stats buffer isn't protected, this can
result in multiple writes and reads at the same time to the same
memory location. This can lead to providing an incorrect value to
the user. Add a mutex to protect against it.
