spi: tegra210-quad: remove redundant error handling code

[ Upstream commit 400d9f1a27cc2fceabdb1ed93eaf0b89b6d32ba5 ]

Remove unnecessary error handling code that terminated transfers and
executed delay on errors. This code was redundant as error handling is
already done at a higher level in the SPI core.
