ASoC: cs35l41: check the return value from spi_setup()

Currently the return value from spi_setup() is not checked for a failure.
It is unlikely it will ever fail in this particular case but it is still
better to add this check for the sake of completeness and correctness. This
is cheap since it is performed once when the device is being probed.

Handle spi_setup() return value.

Found by Linux Verification Center (linuxtesting.org) with Svace.
