Subject: [PATCH v2 4/4] jbd2: Drop pointless shrinker batch initialization

In jbd2_journal_init_common() we set batch size of a shrinker shrinking
checkpointed buffers to journal->j_max_transaction_buffers. But that is
guaranteed to be 0 at that point so we effectively stay with the default
shrinker batch size of 128. It has been like this since introduction of
jbd2 shrinkers so just drop the pointless initialization.
