Subject: [PATCH] qcow_img: Fix warning message.

warning: panic message is not a string literal
  --> qcow_utils/src/qcow_img.rs:52:26
   |
52 |         Err(f) => panic!(f.to_string()),
   |                          ^^^^^^^^^^^^^
   |
   = note: `#[warn(non_fmt_panic)]` on by default
   = note: this is no longer accepted in Rust 2021
help: add a "{}" format string to Display the message
   |
52 |         Err(f) => panic!("{}", f.to_string()),
   |                          ^^^^^
help: or use std::panic::panic_any instead
   |
52 |         Err(f) => std::panic::panic_any(f.to_string()),
   |                   ^^^^^^^^^^^^^^^^^^^^^^
