Merge rust-bitcoin#5015: remove redundant variable in compact_size encoding

11e87e0 remove redundant variable in compact_size encoding (sent deed)

Pull request description:

  Remove unnecessary intermediate variable `v` in the 9-byte encoding branch of `compact_size::encode()`. The variable was assigned `value` and used immediately, adding no functional value
