[VFATLIB] Make Chkdsk handle volume opening locking failures.

Browse source 
For instance, when repair is required, we can ask the caller whether we should
continue or not in case locking failed.
Also, introduced a hack for 1st stage where IopParseDevice() hack is in usage
so that broken NTSTATUS is diverted to appropriate status.
That way, usetup will properly continue even if locking failed (due to its
callback stub!)
