Remove Solaris VFS Hooks

The ZFS code is being restructured to act as a library and a stand
alone module.  This allows us to leverage most of the existing code
with minimal modification.  It also means we need to drop the Solaris
vfs/vnode functions they will be replaced by Linux equivilants and
updated to be Linux friendly.
