hns3 udma: support user-mode TP connection API 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8V1IQ


CVE: NA

--------------------------------------------------------

This patch supports the user-mode TP connection
function in RC mode.
1.In the Jetty creation phase, the TP is created based
  on the sub_trans_mode of user.
2.The urma_get_tpn API is supported.
3.The urma_modify_tp API is supported.

Fixes: 4888db6e ("hns3 udma: support create and destroy JETTY")
