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

mainline inclusion
from mainline-v6.4-rc3
commit 814d0c78
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7WQZ1
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=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.
