USB: rename usb_buffer_alloc() and usb_buffer_free() users
For more clearance what the functions actually do,
usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free() is renamed to usb_free_coherent()
They should only be used in code which really needs DMA coherency.
All call sites have been changed accordingly, except for staging
drivers.
