usb: musb: musbhsdma: drop the controller check in dma_controller_destroy()
This check is hardly required and alas is wrong. 'c' might be NULL but
the chances are low that 'controller' after the container_of() becomes
NULL.
Since no other DMA implementation is doing that and musb-core does not
call it with a NULL pointer it can dropped.
