usb: dwc2: make casts of ep->dma_buf consistent

Browse Source 
In most places in the code we cast this to an unsigned long, but in one
place we cast to an unsigned int.  For consistency and to fix a warning
on 64bit targets, always cast this to unsigned long.  For the long term
we should however change the declaration of dma_buf.
