MFC three change sets (details below) which fix system shutdown and
reboots hanging at "All buffers synced" when using ZFS.

MFC r241556:
Add a KPI to allow to reserve some amount of space in the numvnodes
counter, without actually allocating the vnodes.

For KBI stability, the td_vp_reserv was moved to the end of struct thread

MFC r241628:
zfs: make use of getnewvnode_reserve in zfs_mknode and zfs_zget

MFC r243520, r243521:
zfs: overhaul zfs-vfs glue for vnode life-cycle management
