powerpc/secvar: Fix incorrect return in secvar_sysfs_load()
secvar_ops->get_next() returns -ENOENT when there are no more variables
to return, which is expected behaviour.
Fix this by returning 0 if get_next() returns -ENOENT.
This fixes an issue introduced in commit bd5d9c743d38 ("powerpc: expose
secure variables to userspace via sysfs"), but the return code of
secvar_sysfs_load() was never checked so this issue never mattered.
