DLM: Replace nodeid_to_addr with kernel_getpeername
This patch replaces the call to nodeid_to_addr with a call to kernel_getpeername. This avoids taking a spinlock because it may potentially be called from a softirq context. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>
