kernel: generic: mtdsplit_seil: return 0 instead of -ENODEV

Browse source 
Return 0 if the current mtd is inactive or no valid header/rootfs found,
instead of -ENODEV.
Linux Kernel 6.7 and later versions handle all errors returned by mtd
parsers, including -ENODEV as error. So '0' needs to be returned if no
child partitions were not parsed.
