vfs: prealloc vnodes in getnewvnode_reserve

Having a reserved vnode count does not guarantee that getnewvnodes wont
block later. Said blocking partially defeats the purpose of reserving in
the first place.

Preallocate instaed. The only consumer was always passing "1" as count
and never nesting reservations.
