USB: cleanup for previous patches
This patch (as951) cleans up a few loose ends from earlier patches.
Redundant checks for non-NULL urb->dev are removed, as are checks of
urb->dev->bus (which can never be NULL). Conversely, a check for
non-NULL urb->ep is added to the unlink paths.
A homegrown round-down-to-power-of-2 loop is simplified by using the
ilog2 routine. The comparison in usb_urb_dir_in() is made more
transparent.
