[PATCH V1] PCI: dwc: Fixes N_FTS setup

[Vidya Sagar]

commit aeaa0bfe89654 ("PCI: dwc: Move N_FTS setup to common setup")
unnecessarily uses pci->link_gen in deriving the index to the
n_fts[] array also introducing the issue of accessing beyond the
boundaries of array for greater than Gen-2 speeds. This change fixes
that issue.
