IB/uverbs: Extend create QP to get RWQ indirection table
User applications that want to spread incoming traffic between several WQs should create a QP which contains an indirection table. When such a QP is created other receive side parameters are not valid and should not be given. Its send side is optional and assumed active based on max_send_wr capability value. Extend create QP to work accordingly.
