 vme: Fix error not catched in fake_init()

 In fake_init(), __root_device_register() is possible to fail but it's ignored, which can cause unregistering vme_root fail when exit.

 general protection fault, probably for non-canonical address 0xdffffc000000008c KASAN: null-ptr-deref in range [0x0000000000000460-0x0000000000000467] RIP: 0010:root_device_unregister+0x26/0x60 Call Trace:
