[ Upstream commit ed7bedd2c3ca040f1e8ea02c6590a93116b1ec78 ]
Currently, the VF down state bit is cleared after VF sending link status request command. There is problem that when VF gets link status replied from PF, the down state bit may still set as 1. In this case, the link status replied from PF will be ignored and always set VF link status to down.
To fix this problem, clear VF down state bit before VF requests link status.
