Log message:
	From OPENBSD_3_4
	
	MFC:
	Fix by tedu@
	
	from netbsd:
	Fix a panic that occurred when trying to traverse a corrupt msdosfs
	filesystem.  With this particular corruption, the code in pcbmap()
	would compute an offset into an array that was way out of bounds,
	so check the bounds before trying to access and return an error if
	the offset would be out of bounds.
