cxl: Add missing return statement after handling AFU errror
commit a6130ed253a931d2169c26ab0958d81b0dce4d6e upstream.
We were missing a return statement in the PSL interrupt handler in the
case of an AFU error, which would trigger an "Unhandled CXL PSL IRQ"
warning. We do actually handle these type of errors (by notifying
userspace), so add the missing return IRQ_HANDLED so we don't throw
unecessary warnings.
