PCI: Remove incorrect comment from pci_reassign_resource()

Browse Source 
Commit a4ac9fea01 ("PCI : Calculate right add_size") removed including
min_align into new_size in pci_reassign_resource() which is the correct
thing to do. However, it also added a snakeoil comment that the resource
would already be aligned with min_align which is incorrect.

A resource that is assigned earlier is aligned with the old alignment, NOT
with the new requested alignment (min_align) until later deep within the
reassignment callchain. Thus, remove the incorrect comment.
