MFC r1.90, r1.91:

> - Lock giant when assigning ni_vp and keep vfslocked state valid.

> - Consistently track ni_dvp and ni_vp with dvfslocked and vfslocked rather
>   than trying to optimize it into a single lock.  This adds more calls to
>   lock giant with non smpsafe filesystems but is the only way to reliably
>   hold the correct lock.
> - Remove an invalid assert in the mountedhere case in lookup and fix the
>   code to properly deal with the scenario.  We can actually have a lookup
>   that returns dp == dvp with mountedhere set with certain unmount races.
