genirq: devres: Fix testing return value of request_any_context_irq()
commit 63781394c540dd9e666a6b21d70b64dd52bce76e upstream.
request_any_context_irq() returns a negative value on failure.
It returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED on success.
So fix testing return value of request_any_context_irq().
Also fixup the return value of devm_request_any_context_irq() to make it
consistent with request_any_context_irq().
Fixes: 0668d3065128 ("genirq: Add devm_request_any_context_irq()")
