Subject: [PATCH] IB: Make sure struct ib_user_mad.data is aligned

Make the untyped data region in ib_user_mad have type u64 so that it
gets aligned properly.  This avoids alignment faults in ib_umad when
casting the data field to an rmpp_mad and accessing the 64-bit tid
field on architectures like ia64.
