jbd2: drop pointless shrinker batch initialization

Browse source 
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.
