When doing a camcontrol rescan all or a camcontrol reset all, use the wildcard

path id for enumerating the available busses.  Previously camcontrol was
implicitly passing 0 as the first path id, which meant that if bus 0 was not
present camcontrol would fail with EINVAL instead of rescanning/resetting any
busses that were present.
