util/fifo8: Rename fifo8_pop_buf() -> fifo8_pop_bufptr()
Since fifo8_pop_buf() return a const buffer (which points directly into the FIFO backing store). Rename it using the 'bufptr' suffix to better reflect that it is a pointer to the internal buffer that is being returned. This will help differentiate with methods *copying* the FIFO data.
