Hongjian Dai c98bf3b866 i2c: at91: release DMA channels when probe defers ...

at91_twi_probe_master() can return -EPROBE_DEFER from
at91_init_twi_recovery_info() after at91_twi_configure_dma() has already
claimed the tx/rx DMA channels. at91_twi_probe() then returns without
releasing them, and since dma_request_chan() is not devres-managed the
channels leak on every deferred probe attempt.

Release the channels before deferring the probe.
