spi: cadence-quadspi: fix cleanup of rx_chan on failure paths

commit 04a8ff1bc3514808481ddebd454342ad902a3f60 upstream.

Remove incorrect checks on cqspi->rx_chan that cause driver breakage
during failure cleanup. Ensure proper resource freeing on the success
path when operating in cqspi->use_direct_mode, preventing leaks and
improving stability.
