Stefan Richter 406d6c2a15 firewire: fw-ohci: ignore failure of pci_set_power_state (fix suspend regression)

Minor regression since 2.6.22-rc1:  If the experimental firewire-ohci
driver instead of ohci1394 was loaded, iBook G3 and older PowerBooks
refused to suspend.

Same as commit 5511142870 plus format
string touch-ups from 8a8cea2734,
"firewire: missing newline in printk".  Original patch description:

Fixes (papers over) "Sleep problems with kernels >= 2.6.21 on powerpc",
http://lkml.org/lkml/2007/8/25/155.  The issue is that the FireWire
controller's pci_dev.current_state of iBook G3 and presumably older
PowerBooks is still in PCI_UNKNOWN instead of PCI_D0 when the firewire
driver's .suspend method is called.

Like it was suggested earlier in http://lkml.org/lkml/2006/10/24/13, we
do not fail .suspend anymore if pci_set_power_state failed.
