ocfs2: relax BUG() to ocfs2_error() in __ocfs2_move_extent()
[ Upstream commit 8a7d58845fae061c62b50bc5eeb9bae4a1dedc3d ]
In '__ocfs2_move_extent()', relax 'BUG()' to 'ocfs2_error()' just
to avoid crashing the whole kernel due to a filesystem corruption.
Fixes: 8f603e567aa7 ("Ocfs2/move_extents: move a range of extent.")
