RDMA/cma: Fix endianness bugs
Fix endianness bugs reported by sparse in the RDMA core stack. Note that these are real bugs, but don't affect any existing code to the best of my knowledge. The mlid issue would only affect kernel users of rdma_join_multicast which have the rdma_cm attach/detach its QP. There are no current in tree users that do this. (rdma_join_multicast may be used called by user space applications, which does not have this issue.) And the pkey setting is simply returned as informational.
