Augustin Cavalier 6be5438599 busses/usb: Handle getting/putting the PCI modules properly.
Previously it was possible that we put() them twice, leading to
assert-failure panics as their ref-counts would go below 0.
Now we get() them once for every bus object that we create, as
the destructors put() them.

Should fix the panic in #15004.
