IB/qib: Replace rcu_assign_pointer() with RCU_INIT_POINTER() in qib_keys.c
The uses of "rcu_assign_pointer()" are NULLing out the pointers.
According to RCU_INIT_POINTER()'s block comment:
"1. This use of RCU_INIT_POINTER() is NULLing out the pointer"
it is better to use it instead of rcu_assign_pointer() because it has a
smaller overhead.
The following Coccinelle semantic patch was used:

- rcu_assign_pointer
+ RCU_INIT_POINTER
(..., NULL)
