Remove KMC_KMEM and KMC_VMEM
`KMC_KMEM` and `KMC_VMEM` are now unused since all SPL-implemented
caches are `KMC_KVMEM`.
KMC_KMEM: Given the default value of `spl_kmem_cache_kmem_limit`, we
don't use kmalloc to back the SPL caches, instead we use kvmalloc
(KMC_KVMEM). The flag, module parameter, /proc entries, and associated
code are removed.
KMC_VMEM: This flag is not used, and kvmalloc() is always preferable to
vmalloc(). The flag, /proc entries, and associated code are removed.
