[PATCH-resend] checkpatch: add __rcu as a sparse modifier

[Sven Eckelmann]

Fix "need consistent spacing around '*'" error after a __rcu sparse
annotation which was caused by the missing __rcu entry in the
checkpatch.pl internal list of sparse keywords.

I reported that problem 2 1/2 months ago and then send the patch 3 weeks
ago, but never got a reaction. Therefore I resend the patch to Andrew
Morton instead of Andy Whitcroft. He seems to have been responsible for
the last checkpatch.pl-patches.

Btw. thanks Eric Dumazet for the Acked-by.
