ocfs2: Do not downconvert if the lock level is already compatible During upconvert, if the master were to send a BAST, dlmglue will detect the upconversion in process and send a cancel convert to the master. Upon receiving the AST for the cancel convert, it will re-process the lock resource to determine whether it needs downconverting. Say, the up was from PR to EX and the BAST was for EX. After the cancel convert, it will need to downconvert to NL. However, if the node was originally upconverting from NL to EX, then there would be no reason to downconvert (assuming the same message sequence). This patch makes dlmglue consider the possibility that the current lock level is already compatible and that downconverting is not required.
