Conditionally remove all cached extents belonging to an inode
when truncating its inline data.  It's only necessary to attempt to
remove cached extents when a conversion from inline to extent storage
has been initiated (!EXT4_STATE_MAY_INLINE_DATA).  This avoids
unnecessary es lock overhead in the more common inline case.
