firewire: ohci: release channel in error path
firewire-ohci keeps book of which isochronous channels are occupied by
IR DMA contexts, so that there cannot be more than one context listening
to a certain channel.
If IR context creation failed due to an out-of-memory condition, this
bookkeeping leaked a channel.
