ocfs2_dlm: Cookies in locks not being printed correctly in error messages
The dlm encodes the node number and a sequence number in the lock cookie. It also stores the cookie in the lockres in the big endian format to avoid swapping 8 bytes on each lock request. The bug here was that it was assuming the cookie to be in the cpu format when decoding it for printing the error message. This patch swaps the bytes before the print.
