spi: synquacer: Fix timeout handling in synquacer_spi_transfer_one()
wait_for_completion_timeout() never returns a <0 value. It returns either
on timeout or a positive value (at least 1, or number of jiffies left
till timeout)

So, fix the error handling path and return -ETIMEDOUT should a timeout
occur.

Fixes: b0823ee35cf9 ("spi: Add spi driver for Socionext SynQuacer platform")
