ocfs2: don't use handle for locking in allocation functions
Instead we record our state on the allocation context structure which all callers already know about and lifetime correctly. This means the reservation functions don't need a handle passed in any more, and we can also take it off the alloc context. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
