Net / e100: Fix suspend of devices that cannot be power managed

Browse Source 
If the adapter is not power-manageable using either ACPI, or the
native PCI PM interface, __e100_power_off() returns error code, which
causes every attempt to suspend to fail, although it should return 0
in such a case.  Fix this problem by ignoring the return value of
pci_set_power_state() in __e100_power_off().
