  Log:
   - Remove vnode lock asserts at the end of vfs syscalls.  These asserts were
     used to ensure that we weren't exiting the syscall with a lock still
     held.  This wasn't safe, however, because we'd already executed a vput()
     and on a loaded system the vnode may have been free'd by the time we
     assert.  This functionality is also handled by the td_locks assert in
     userret, which doesn't tell you what the syscall was, but will at least
     panic before you deadlock.
