Correctly set loopfilter mask to zero

1. Set loopfilter mask to zero after they're used in loopfiltering,
instead of set them to zero at the beginning of decoding a tile,
which could incorrectly earase mask information when a tile is
not totally coded.

2. Silence a warning that a pointer may not be used when it reaches
boundary of a block.
