btrfs: only clear EXTENT_LOCK bit in extent_invalidatepage
extent_invalidatepage() will try to clear all possible bits since it's
calling clear_extent_bit() with delete == 1.
This is currently fine, since for btree io tree, it only utilizes
EXTENT_LOCK bit. But this could be a problem for later subpage support,
which will utilize extra io tree bit to represent additional info.
This patch will just convert that clear_extent_bit() to
unlock_extent_cached().
For current code since only EXTENT_LOCKED bit is utilized, this doesn't
change the behavior, but provides a much cleaner basis for incoming
subpage support.
