[PATCH] jbd2: Always set journal superblock checksum when writingout superblock

[Darrick J. Wong]

Add a few missing calls to jbd2_superblock_csum_set just prior to calling
jbd2_write_superblock.  This fixes complaints about corrupt journals if
metadata checksumming and journal checksumming are both enabled.
