net: stmmac: fix pm runtime issue in stmmac_dvr_remove()
If netif is running when stmmac_dvr_remove is invoked,
the unregister_netdev will call ndo_stop(stmmac_release) and
vlan_kill_rx_filter(stmmac_vlan_rx_kill_vid).
Currently, stmmac_dvr_remove() will disable pm runtime before
unregister_netdev. When stmmac_vlan_rx_kill_vid is invoked,
pm_runtime_resume_and_get in it returns EACCESS error number,
and reports:
dwmac-mediatek 11021000.ethernet eth0: stmmac_dvr_remove: removing driver
dwmac-mediatek 11021000.ethernet eth0: FPE workqueue stop
dwmac-mediatek 11021000.ethernet eth0: failed to kill vid 0081/0
Move the pm_runtime_disable to the end of stmmac_dvr_remove
to fix this issue.
