powerpc/xive: fix return value of __setup handler
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings.
Also, error return codes don't mean anything to obsolete_checksetup() --
only non-zero (usually 1) or zero. So return 1 from xive_off() and
xive_store_eoi_cmdline().
Fixes: 243e25112d06 ("powerpc/xive: Native exploitation of the XIVE interrupt controller")
Fixes: c21ee04f11ae ("powerpc/xive: Add a kernel parameter for StoreEOI")
