PCI/MSI: Remove pci_enable_msi_block()
There are no users of pci_enable_msi_block() function left. Obsolete it in favor of pci_enable_msi_range() and pci_enable_msi_exact() functions. Previously, we called arch_setup_msi_irqs() once, requesting the same vector count we passed to arch_msi_check_device(). Now we may call it several times: if it returns failure, we may retry and request fewer vectors. We don't keep track of the vector count we initially passed to arch_msi_check_device(). We only keep track of the number of vectors successfully set up by arch_setup_msi_irqs(), and this is what we use to clean things up when disabling MSI. Therefore, we assume that arch_msi_check_device() does nothing that will have to be cleaned up later.
