Log:
MFC: Eliminate a deadlock when creating snapshots. Blocking
vn_start_write() must be called without any vnode locks held.
Remove calls to vn_start_write() and vn_finished_write() in
vnode_pager_putpages() and add these calls before the vnode lock
is obtained to most of the callers that don't already have them.
