powerpc/powernv/opal-dump : Use IRQ_HANDLED instead of numbers in interrupt handler
commit b29336c0e1785a28bc40a9fd47c2321671e9792e upstream.
Fixes: 8034f715f ("powernv/opal-dump: Convert to irq domain")
Converts all the return explicit number to a more proper IRQ_HANDLED,
which looks proper incase of interrupt handler returning case.
Here, It also removes error message like "nobody cared" which was
getting unveiled while returning -1 or 0 from handler.
