Input: ads7846 - do not attempt IRQ workaround when deferring probe

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

When request_irq() returns -EPORBE_DEFER we should abort probe and try
again later instead of trying to engage IRQ trigger workaround.
