Multiple race conditions are possible between PCI hotplug and the generic
PCI bus rescan and device removal that can be triggered via sysfs.

To avoid those race conditions make PCI hotplug use global PCI
rescan-remove locking.

Fix whitespace, capitalization, and spelling errors.  No functional change.
I know "busses" is not an error, but "buses" was more common, so I used it
consistently.

The old pci_remove_bus_device actually did stop and remove.

Make the name reflect that to reduce confusion.

This patch is done by sed scripts and changes back some incorrect
__pci_remove_bus_device changes.

Convert uses of pci_find_slot to modern API.

In the conversion sites, we end up calling pci_dev_put() right away.

This may seem like it misses the entire point of doing something like
pci_get_bus_and_slot(), since we drop the reference so soon, but it turns
out we don't actually do much with the returned pci_dev.

I plan on untangling cpqphp further, but clearly cpqphp never worried too
much about a properly refcounted pci_dev anyway. For now, this conversion
seems reasonable, as it gets rid of the last in-tree caller of pci_find_slot.

I have no clue what the original intent here was, but the code as
written is useless.

The old dbg() statement above the old callsite might lead one to think
that at one point, there was supposed to be some recursion, but any
sense of sanity here has been lost to the ravages of time.

Instead of making multiple calls to pcibios_get_irq_routing_table, let's
just do it once and save the answer.

The reason we were making multiple calls is because we liked to calculate
its length and perform some loop over it. Instead of open-coding the length
calculation every time, provide it in an inline helper function.

Finally, since pci_print_IRQ_route() is used only for debug, let's only
do it when cpqhp_debug is set.
