RDMA/efa: Expose 64-bit send WR ID support to userspace

Browse source

Currently EFA WRs support 16-bit request ID, this requires EFA to manage
a translation table to translate the IB WR ID from 64-bits to 16-bits
and translating it back on CQ completion.
Expose a new device capability to handle 64-bit request ID for SQ WRs
allowing userspace to directly post the 64-bit ID to the device.
