Subject: RDMA/uverbs: Fix typo of sizeof argument
From: Konstantin Meskhidze <konstantin.meskhidze@xxxxxxxxxx>
commit c489800e0d48097fc6afebd862c6afa039110a36 upstream.
Since size of 'hdr' pointer and '*hdr' structure is equal on 64-bit
machines issue probably didn't cause any wrong behavior. But anyway,
fixing of typo is required.
