r8169: do not bring device down when suspending
r8169: do not bring device down when suspending

Stopping all activity through ChipCmd and blindly acking the irqs
is neither nice nor completely needed: the transition to low-power
mode does enough work and it apparently keeps the device in a sane
state.

Patch suggested by a fix for http://bugzilla.kernel.org/show_bug.cgi?id=9512

The rtl_shutdown path is kept unchanged so far.
