net: hibmcge: fix not restore rx pause mac addr after reset issue

The MAC hardware supports receiving two types of
pause frames from link partner.
One is a pause frame with a destination address
of 01:80:C2:00:00:01.
The other is a pause frame whose destination address
is the address of the hibmcge driver.

01:80:C2:00:00:01 is supported by default.

In .ndo_set_mac_address(), the hibmcge driver calls
.hbg_hw_set_rx_pause_mac_addr() to set its mac address as the
destination address of the rx puase frame.
Therefore, pause frames with two types of MAC addresses can be received.

Currently, the rx pause addr does not restored after reset.
As a result, pause frames whose destination address is
the hibmcge driver address cannot be correctly received.

This patch restores the configuration by calling
.hbg_hw_set_rx_pause_mac_addr() after reset is complete.
