RDMA/efa: Set maximum pkeys device attribute

[ Upstream commit 0133654d8eb8607eacc96badfe49bf992155f4cb ]

The max_pkeys device attribute was not set in query device verb, set it to
one in order to account for the default pkey (0xffff). This information is
exposed to userspace and can cause malfunction
