dmaengine: sh: rz-dmac: Fix rz_dmac_terminate_all()

After audio full duplex testing, playing the recorded file contains a few
playback frames from the previous time. The rz_dmac_terminate_all() does
not reset all the hardware descriptors queued previously, leading to the
wrong descriptor being picked up during the next DMA transfer. Fix the
above issue by resetting all the descriptor headers for a channel in
rz_dmac_terminate_all() as rz_dmac_lmdesc_recycle() points to the proper
descriptor header filled by the rz_dmac_prepare_descs_for_slave_sg().
