net: arc_emac: reset txbd_curr and txbd_dirty pointers to zero
EMAC reset internal tx ring pointer to zero at statup.
txbd_curr and txbd_dirty can be different from zero.
That cause ethernet transfer hang (no packets transmitted).
In order to reproduce, run on device:
ifconfig eth0 down
ifconfig eth0 up
