ofed: mask seq_num identifier to occupy only 3 bytes
The seq_num among other things is used to assign rq_psn value, which is
a 24-bit identifier.  When the seq_num is full 4-byte value, we are
usually receiving: '_ib_modify_qp rq_psn overflow, masking to 24 bits'
warning.

This is burdensome for running rdma traffic with large number of
connections, because the number of logs is growing fast.
