The NULL assignment was more about making it clear that
__free(pci_dev_put) will take no action until the pdev is acquired.
Otherwise, any future refactoring that introduces a 'return' before
@pdev is acquired needs to be careful to assign @pdev to NULL. So, just
include it in the declaration more as a __free() declaration style issue
than a correctness issue.
