jbd2: don't leak memory if setting up journal fails

commit cd9cb405e0b948363811dc74dbb2890f56f2cb87 upstream.

In journal_init_common(), if we failed to allocate the j_wbuf array, or
if we failed to create the buffer_head for the journal superblock, we
leaked the memory allocated for the revocation tables.  Fix this.
