pci: fix PCI bus allocation alignment handling
In commit 13583b16592a ("PCI: refactor io size calculation code") Ram had a thinko in the refactorization of the code: the end result used the variable 'align' for the bus alignment, but the original code used 'min_align'. Since then, another use of that 'align' variable got introduced by commit c8adf9a3e873 ("PCI: pre-allocate additional resources to devices only after successful allocation of essential resources.") Fix both of those uses to use 'min_align' as they should.
