PCI: dwc: Fix n_fts[] array overrun

Browse source

[ Upstream commit 6611036128 ]

commit aeaa0bfe89 ("PCI: dwc: Move N_FTS setup to common setup")
incorrectly 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.
