net: hns3: fix reset delay time to avoid configuration timeout



[ Upstream commit 814d0c786068e858d889ada3153bff82f64223ad ]

Currently the hns3 vf function reset delays 5000ms before vf rebuild
process. In product applications, this delay is too long for application
configurations and causes configuration timeout.

According to the tests, 500ms delay is enough for reset process except PF
FLR. So this patch modifies delay to 500ms in these scenarios.
