usb-ehci: Remove dead nakcnt code
This patch removes 2 bits of dead nakcnt code: 1) usb_ehci_execute calls ehci_qh_do_overlay which does: nakcnt = reload; and then has a block of code which is conditional on: if (reload && !nakcnt) { which ofcourse is never true now as nakcnt == reload. 2) ehci_state_fetchqh does: nakcnt = reload; but before nakcnt is ever used ehci_state_fetchqh is always followed by a ehci_qh_do_overlay call which also does: nakcnt = reload; So doing this from ehci_state_fetchqh is redundant.
