audio: intel-hda: check stream entry count during transfer
Intel HDA emulator uses stream of buffers during DMA data transfers. Each entry has buffer length and buffer pointer position, which are used to derive bytes to 'copy'. If this length and buffer pointer were to be same, 'copy' could be set to zero(0), leading to an infinite loop. Add check to avoid it.
