genirq: devres: Fix testing return value of request_any_context_irq()

Browse Source 
commit 63781394c5 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: 0668d30651 ("genirq: Add devm_request_any_context_irq()")
