Geert Uytterhoeven 6bab2c613d genirq: Correct fuzzy and fragile IRQ_RETVAL() definition
commit bedd30d986 ("genirq: make irqreturn_t an enum") blindly replaced
"0" by "IRQ_NONE" in the "IRQ_RETVAL(x)" macro definition.

However, as "x" is a condition, "0" meant "boolean false", not an
irqreturn_t value.

All of this worked, and kept working after the addition of IRQ_WAKE_THREAD,
as
  - both "boolean false" and "IRQ_NONE" are "0" (for the comparison),
  - "boolean true" and "boolean false" nicely map to the correct values of
    "IRQ_HANDLED" and "IRQ_NONE" (for the return value).

Correct the macro definition for clarity and future-proofness.
