OpenZFS on Linux and FreeBSD

Mark Johnston 57f43735ca Fix several bugs in the FreeBSD rename VOP implementation
- To avoid a use-after-free, zfsvfs->z_log needs to be loaded after the
  teardown lock is acquired with ZFS_ENTER().
- Avoid leaking vnode locks in zfs_rename_relock() and zfs_rename_()
  when the ZFS_ENTER() macros forces an early return.

Refactor the rename implementation so that ZFS_ENTER() can be used
safely.  As a bonus, this lets us use the ZFS_VERIFY_ZP() macro instead
of open-coding its implementation.
