[PATCH] usb: host: ehci-generic: Fix error check

[Andre Przywara]

Commit 81755b8c20fe ("usb: host: ehci-generic: Make resets and clocks
optional") improved the error check to cover the reset property being
optional. However this was using the wrong error variable for the
check, so would now never fail.

Use the correct error variable for checking the result of
reset_get_bulk(), to actually report genuine errors.

Hi,

apologies for messing up this simple patch of mine last month. I got
confused by the mixed usage of "ret" and "err" in this function. This
might endorse some cleanup, but I don't dare to touch this file again,
especially not that late in the cycle.

Cheers,
Andre
