fdc: fix FD_SR0_SEEK for non-DMA transfers and multi sectors transfers 

On non-DMA transfers, fdctrl_stop_transfer() used to set FD_SR0_SEEK
no matter if there actually was a seek or not. This is obviously wrong.

fdctrl_seek_to_next_sect() has this information because it performs
the seek itself.
