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.
