Tim Kientzle 763d9566fe Clear entire map structure including locks so that the
locks don't accidentally appear to have been already
initialized.

In particular, this fixes a consistent kernel crash on
armv6 with:
  panic: lock "vm map (user)" 0xc09cc050 already initialized
that appeared with r251709.
