7fde2dbe03 RDMA/irdma: Fix issues with u8 left shift operation 
The shifting of the u8 integer info->map[i] the left will be promoted
to a 32 bit signed int and then sign-extended to a u64. In the event
that the top bit of the u8 is set then all then all the upper 32 bits
of the u64 end up as also being set because of the sign-extension.
Fix this by casting the u8 values to a u64 before the left shift. This

Add definitions for managing the RDMA HW work scheduler (WS) tree.

A WS node is created via a control QP operation with the bandwidth
allocation, arbitration scheme, and traffic class of the QP specified.
The Qset handle returned associates the QoS parameters for the QP.
The Qset is registered with the LAN and an equivalent node is created
in the LAN packet scheduler tree.
