Vivian Wang 5556f23478 net: spacemit: Check netif_running() in emac_set_pauseparam() ...

Currently, emac_set_pauseparam() will oops if userspace calls it while
the interface is not up, because phydev is NULL, but it is still
accessed in emac_set_fc() and emac_set_fc_autoneg().

Check for netif_running(dev) in emac_set_pauseparam() before proceeding.
