Review comment:
Changes of the OMKeyCommitRequest are not required. The original logic
has ensure correctedSpace is correct.
`long correctedSpace = omKeyInfo.getDataSize() * factor - allocatedSize;`
When the key length is 0:
`long correctedSpace = 0 * factor - allocatedSize;`
Just change BlockOutputStreamEntryPool, the added UT should also run
normally.
