[patch v6 6/7] PCI/MSI: Remove obsolete sanity checks for multiple interrupt sets

[Thomas Gleixner]

Multiple interrupt sets for affinity spreading are now handled in the core
code and the number of sets and their size is recalculated via a driver
supplied callback.

That avoids the requirement to invoke pci_alloc_irq_vectors_affinity() with
the arguments minvecs and maxvecs set to the same value and the callsite
handling the ENOSPC situation.

Remove the now obsolete sanity checks and the related comments.
