usb: xhci: clean up handling of upper bits in SetPortFeature wIndex

In Set Port Feature requests, the upper byte of 'wIndex' encodes
feature-specific parameters. The current code reads these upper bits in
an early pre-processing block, and then the same feature is handled again
later in the main switch statement. This results in duplicated condition
checks and makes the control flow harder to follow.

Move all feature-specific extraction of 'wIndex' upper bits into the
main SetPortFeature logic so that each feature is handled in exactly one
place. This reduces duplication, makes the handling clearer, and keeps
'wIndex' parsing local to the code that actually uses the values.
