jbd2: fix infinite loop when recovering corrupt journal blocks
commit 022eaa7517017efe4f6538750c2b59a804dc7df7 upstream.
When recovering the journal, don't fall into an infinite loop if we
encounter a corrupt journal block. Instead, just skip the block and
return an error, which fails the mount and thus forces the user to run
a full filesystem fsck.
