If some error happens in NCP_IOC_SETROOT ioctl, the appropriate error
return value is then (in most cases) just overwritten before we return.
This can result in reporting success to userspace although error
happened. This bug was introduced by commit 2e54eb96e2c8 (BKL: Remove
BKL from ncpfs). Propagate the errors correctly.
