get_next_buf() and vbi_get_next_buf() do exactly the same just with a
different dma queue and buffer. Saving the new buffer pointer back to the
device struct in em28xx_urb_data_copy() instead of doing this from inside
these functions makes it possible to get rid of one of them.
Also refactor the function parameters and return type:
- pass a pointer to struct em28xx as parameter (instead of obtaining the
pointer from the dma queue pointer with the container_of macro) like we do
it in all other functions
- instead of using a pointer-pointer, return the pointer to the new buffer
as return value of the function
