Subject: [PATCH] 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.
