Subject: [PATCH 3/3] net-dccp: Suppress warning about large allocations from DCCP

The DCCP protocol tries to allocate some large hash tables during
initialisation using the largest size possible.  This can be larger than
what the page allocator can provide so it prints a warning. However, the
caller is able to handle the situation so this patch suppresses the warning.
