Michael Ellerman 928f4c526c powerpc/powernv: Free name on error in opal_event_init() ...

[ Upstream commit cf8989d20d64ad702a6210c11a0347ebf3852aa7 ]

In opal_event_init() if request_irq() fails name is not freed, leading
to a memory leak. The code only runs at boot time, there's no way for a
user to trigger it, so there's no security impact.

Fix the leak by freeing name in the error path.
