maple: fix wrong return value of maple_bus_init().
[ Upstream commit bde82ee391fa6d3ad054313c4aa7b726d32515ce ]
If KMEM_CACHE or maple_alloc_dev failed, the maple_bus_init() will return 0
rather than error, because the retval is not changed after KMEM_CACHE or
maple_alloc_dev failed.
Fixes: 17be2d2b1c33 ("sh: Add maple bus support for the SEGA Dreamcast.")
