Subject: [PATCH] xen/pciback: Document when the 'unbind' and 'bind' functions
 are called.

And also mention that you cannot do any pci_reset_function,
pci_reset_slot, or such calls. This is because they take the same
lock as SysFS does - and we would end up with a dead-lock if
we call those functions.
