IB/hfi1: Add mmu_rb_node refcount to hfi1_mmu_rb_template tracepoints

Browse source

Add kref_read() of mmu_rb_node.refcount in hfi1_mmu_rb_template-type
tracepoint output.

Change hfi1_mmu_rb_template tracepoint to take a struct mmu_rb_node* and
record the values it needs from that. This makes the trace_hfi1_mmu*()
calls shorter and easier to read.

Add hfi1_mmu_release_node() tracepoint before all
mmu_rb_node->handler->ops->remove() calls.

Make hfi1_mmu_rb_search() tracepoint its own tracepoint type separate
from hfi1_mmu_rb_template since hfi1_mmu_rb_search() does not take a
struct mmu_rb_node*.
