kernel - Fix various memory & swap leaks in tmpfs
* tmpfs was using a vref() instead of a vget() (cache_vget() to be precise)
which does not necessarily reactivate an inactive vnode. This can cause
the vnode to languish in the vnode cache even when the underlying file
has been removed and no longer has any open() descriptors.
* tmpfs_nrmdir(), tmpfs_nremove(), and tmpfs_nrename() (for target
replacement
renames) was effected.
