USB: remove excess code from hub.c
This patch (as917) removes a now-unnecessary level of subroutine nesting from hub.c. Since usb_port_suspend() does nothing but call hub_port_suspend(), and usb_port_resume() does nothing but call hub_port_resume(), there's no reason to keep the routines separate. Also included in the patch are a few cosmetic changes involving whitespace and use of braces.
