firewire: Survive more than 256 bus resets
The "color" is used during the topology building after a bus reset, hovever in "struct fw_node"s it is stored in a u8, but in struct fw_card it is stored in an int. When the value wraps in one struct, but not the other, disaster strikes. Signed-off-by: Jay Fenlason <fenlason@redhat.com> Fixes http://bugzilla.kernel.org/show_bug.cgi?id=10922.
