Modified Files:
	src/sys/fs/msdosfs: msdosfs_fat.c

Log Message:
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.
