RDMA/rxe: Enable MW object pool
Currently the rxe driver has a rxe_mw struct object but nothing about
memory windows is enabled. This patch turns on memory windows and some
minor cleanup.
Set device attribute in rxe.c so max_mw = MAX_MW. Change parameters in
rxe_param.h so that MAX_MW is the same as MAX_MR. Reduce the number of
MRs and MWs to 4K from 256K. Add device capability bits for 2a and 2b
memory windows. Removed RXE_MR_TYPE_MW from the rxe_mr_type enum.
