Subject: spi: a3700: Return correct value on timeout detection

From: Maxime Chevallier <maxime.chevallier@smile.fr>

commit 5a866ec0014b2baa4ecbb1eaa19c835482829d08 upstream.

When waiting for transfer completion, a3700_spi_wait_completion
returns a boolean indicating if a timeout occurred.

The function was returning 'true' everytime, failing to detect any
timeout.

This patch makes it return 'false' when a timeout is reached.
