net: hns3: fix for mishandle of asserting VF reset fail 

When asserts VF reset fail, flag HCLGEVF_STATE_CMD_DISABLE
and handshake status should not set, otherwise the retry will
fail. So adds a check for asserting VF reset and returns
directly when fails.

Fixes: ef5f8e507e ("net: hns3: stop handling command queue while resetting VF")
