remove kmem_cache module parameter KMC_EXPIRE_AGE
By default, `spl_kmem_cache_expire` is `KMC_EXPIRE_MEM`, meaning that
objects will be removed from kmem cache magazines by
`spl_kmem_cache_reap_now()`.

There is also a module parameter to change this to `KMC_EXPIRE_AGE`,
which establishes a maximum lifetime for objects to stay in the
magazine.  This setting has rarely, if ever, been used, and is not
regularly tested.

This commit removes the code for `KMC_EXPIRE_AGE`, and associated module
parameters.

Additionally, the unused module parameter
`spl_kmem_cache_obj_per_slab_min` is removed.
