soundwire: cadence: remove automatic command retries 

This is a good idea on paper, but it's not recommended at all when
operating in multi-master mode. It's also not recommended when doing
bank switches, since the retransmission would happen at the next SSP,
and the command protocol is stuck in the mean time.
