firewire: ohci: consolidate context status flags
"firewire: ohci: restart iso DMA contexts on resume from low power mode" added the flag struct context.active and "firewire: ohci: cache the context run bit" added struct context.running. These flags contain the same information; combine them. Also, normalize whitespace in pci_resume(). Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
