spi: Deal with slaves that return from transfer_one() unfinished
Some drivers, such as spi-pxa2xx return from the transfer_one callback immediately, idicating that the transfer will be finished asynchronously. Normally, spi_transfer_one_message() synchronously waits for the transfer to finish with wait_for_completion_timeout(). For slaves, we don't want the transaction to time out as it can complete in a long time in future. Use wait_for_completion_interruptible() instead.
