RDMA/hns: Fix init check of VFs on RoCE bonding slaves

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8QLD3



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

This patch makes 2 changes for check_vf_support():

1. add check of RDMA over UBLink VFs before check_vf_support(), since
VFs in this case will never be of RoCE bonding slaves.

2. since RDMA over UBLink VFs won't enter check_vf_support() anymore, the
return value is changed to false when the PF doesn't have a corresponding
hr_dev so that VFs init can be correctly blocked on those non-main_hr_dev
slaves.
