firewire: fix NULL pointer deref. and resource leak

By supplying ioctl()s in the wrong order, a userspace client was able to
trigger NULL pointer dereferences.  Furthermore, by calling
ioctl_create_iso_context more than once, new contexts could be created
without ever freeing the previously created contexts.

Thanks to Anders Blomdell for the report.
