os/bluestore: do not assign already cached buffer to
mempool_bluestore_writing.

This spoils mempool stats with unexpectedly high mount of entries in
the bluestore_writing mempool.
The issue might occurs while handling partial overwrites in EC pools.
Unser some circumstances EC backend might rewrite data from read cache back to disk.
