usb: xhci: Remove skip_isoc_td()

This function is pointless because usb_submit_urb() initializes all
isoc frame descriptors to -EXDEV and 0 length so that HCDs don't need
to do anything with transfers which were never executed.

Other HCDs rely on this (e.g. EHCI itd_complete()), so we can too.
This gets rid of a potentially dangereous function which could corrupt
memory if we weren't super careful to only call it on isoc URBs.

Also, set status to 0 rather than any random status determined by the
later TD which caused skipping. This status will be ignored anyway.
