kernel - Fix improper unlock/relock sequence in HAMMER
* VOP_FSYNC() can be called during a vnode inactivation or reclaim.
In this case the vnode lock absolutely cannot be released or it
can create a window of opportunity for another thread that results
in a panic.
* Fixes a NFS server crash when multiple clients are trying to
delete/create/write the same file at the same time.
