freebsd stable - Jun 2012 - Diskless ignore remount - fix (Re: conf/158127: [patch] remount_optional option in rc.initdiskless doesn' t actually work)

I notice that PR 158127 remains outstanding, June, 2011.  I've enclosed a
patch for Stable 9.0, to correct diskless booting.  When a mountpoint
fails, the failure may be ignored as required/documented.

The patch has been tested with/without /conf/default/etc/remount_optional &
is functionally correct. 

It would be appreciated if someone would verify and commit.
