RDMA/uverbs: Don't fail in creation of multiple flows
The conversion from offsetof() calculations to sizeof()
wrongly behaved for missed exact size and in scenario with
more than one flow.
In such scenario we got "create flow failed, flow 10: 8 bytes
left from uverb cmd" error, which is wrong because the size of
kern_spec is exactly 8 bytes, and we were not supposed to fail.
Cc: <stable@vger.kernel.org> # 3.12
