Kishon Vijay Abraham I 06d9db7273 usb: musb: gadget: do *unmap_dma_buffer* only for valid DMA addr
musb does not use DMA buffer for ep0 but it uses the same giveback
function *musb_g_giveback* for all endpoints (*musb_g_ep0_giveback* calls
*musb_g_giveback*). So for ep0 case request.dma will be '0'
and will result in kernel OOPS if tried to *unmap_dma_buffer* for requests in
ep0. Fixed it by doing *unmap_dma_buffer* only for valid DMA addr and
checking that musb_ep->dma is valid when unmapping.
