Subject: IB: remove xrc_remote_srq_num from struct ib_send_wr
X-Git-Tag: v4.4-rc1~78^2~29^2^2

IB: remove xrc_remote_srq_num from struct ib_send_wr

The field is only initialized in mlx, but never used.

If we want to add proper XRC support it should be done with a new
struct ib_xrc_wr.

This shrinks the various WR structures by another 4 bytes.
