jbd2: Avoid long replay times due to high number or revoke blocks

jbd2: Avoid long replay times due to high number or revoke blocks

Some users are reporting journal replay takes a long time when there is
excessive number of revoke blocks in the journal. Reported times are
like:

1048576 records - 95 seconds
2097152 records - 580 seconds

The problem is that hash chains in the revoke table gets excessively
long in these cases. Fix the problem by sizing the revoke table
appropriately before the revoke pass.

Thanks to Alexey Zhuravlev <azhuravlev@ddn.com> for benchmarking the
patch with large numbers of revoke blocks [1].
