GFS2: Don't withdraw on partial rindex entries 

ince gfs2 writes the rindex file a block at a time, and releases the
exclusive lock after each block, it is possible that another process
will grab the lock in the middle of the write.  Since rindex entries are
not an even divisor of blocks, that other process may see partial
entries.  On grows, this is fine.  The process can simply ignore the the
partial entires. Previously, the code withdrew when it saw partial
entries. Now it simply ignores them.
