r8169: reset IntrStatus after chip reset
Original comment (Karsten):
On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time
after BIOS has run, IntrStatus reads 5 after chip has been reset.
IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen
after chip reset instead of before.
Remark (Francois):
Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR,
the bug reveals itself with a typical "interrupt 0025 in poll" message
at startup. In retrospect, the message should had been read as an hint of
an unexpected hardware state several months ago :o(
