This enum is used by ibv_query_device_ex(3) so it should be defined
in include/uapi/rdma/ib_user_verbs.h.

1)Part of enum ib_device_cap_flags are used by ibv_query_device(3)
  or ibv_query_device_ex(3), so we define them in
  include/uapi/rdma/ib_user_verbs.h and only expose them to userspace.

2)Reformat enum ib_device_cap_flags by removing the indent before '='.
