kernel - Optimize the x86-64 lwbuf API
* Change lwbuf_alloc(m) to lwbuf_alloc(m, &lwb_cache), passing a pointer to
a struct lwb which lwbuf_alloc() may used if it desires.
* The x86-64 lwbuf_alloc() now just fills in the passed lwb and returns it.
The i386 lwbuf_alloc() still uses the objcache w/ its kva mappings. This
removes objcache calls from the critical path.
* The x86-64 lwbuf_alloc()/lwbuf_free() functions are now inlines (ALL x86-64
lwbuf functions are now inlines).
