staging: lustre: obdclass: don't require lct_owner to be non-NULL.
Some places in lu_object.c allow lct_owner to be NULL, implying that the code is built in to the kernel (not a module), but two places don't. This prevents us from building lustre into the kernel. So remove the requirement and always allow lct_owner to be NULL. This requires removing an "assert" that the module count is positive, but this is redundant as module_put() already does the necessary test.
