IB/core: Add creation flags to struct ib_qp_init_attr
Add a create_flags member to struct ib_qp_init_attr that will allow a kernel verbs consumer to create a pass special flags when creating a QP. Add a flag value for telling low-level drivers that a QP will be used for IPoIB UD LSO. The create_flags member will also be useful for XRC and ehca low-latency QP support. Since no create_flags handling is implemented yet, add code to all low-level drivers to return -EINVAL if create_flags is non-zero.
