rhashtable: Still do rehash when we get EEXIST ...
[ Upstream commit 408f13ef358aa5ad56dc6230c2c7deb92cf462b1 ]
As it stands if a shrink is delayed because of an outstanding
rehash, we will go into a rescheduling loop without ever doing
the rehash.
This patch fixes this by still carrying out the rehash and then
rescheduling so that we can shrink after the completion of the
rehash should it still be necessary.
The return value of EEXIST captures this case and other cases
(e.g., another thread expanded/rehashed the table at the same
time) where we should still proceed with the rehash.
