GEODE-1885: Removed call to check readiness (region check) after the offheap
region entry is released.
GEODE-1885: Missing subsctiption event with Offheap partitioned region during
bucket rebalance.
During the trasaction commit on redundant bucket region, if the bucket region
is moved, the call-back logic (to deliver subscription events) were not invoked
due to check-readiness call with offheap region. The check-readiness throws
exception, if the region is not found, which causes the code to return early
without sending the subscription events.
In this scenario, calling check-readiness is not needed...

> During transaction operation, if there is concurrent redundant bucket
> re-balance is in progress, the client can miss a subscription event, if its
> primary queue is hosted on the node where bucket gets moved from.
> Consider, three node cluster N1, N2 and N3. With:
> - Client C1 connected to node N2.
> - Primary bucket region B1 on N1. And secondary bucket for B1 on N2.
> - A Transaction is started on N2, which creates a entry on B1.
> - When the TX is committed. At the same time the Bucket B1 on N2 is moved to
> N3.
> - The Tx commit message from N1 is sent to N2. This also includes the
> subscription message, satisfying the client C1.
> - On N2, for offheap region, when bucket is not found locally, the exception
> response is sent to back to N1 without processing the subscription message.
