Michael J. Ruhl f2a3bc00a0 IB/hfi1: Protect context array set/clear with spinlock 
The rcd array can be accessed from user context or during interrupts.
Protecting this with a mutex isn't a good idea because the mutex should
not be used from an IRQ.

Protect the allocation and freeing of rcd array elements with a
spinlock.
