param 'txn' not used in function maybe_send_schema()

[houzj.f...@fujitsu.com]

Hi,

When reviewing logicalreplication related patches, I noticed the function
param ReorderBufferTXN *txn not used in the function maybe_send_schema(). Since
this is not an external function, I think it might be better to remove the 
unused paramater.

Best regards,
