[PATCH v2 0/2] tcg: Jump after always false condition

[Samuel Tardieu]

Unreachable code in an error handling block is listed in issue
https://gitlab.com/qemu-project/qemu/-/issues/2030.

After removing this code, the `fail` label is now immediately followed
by a test whose condition can never be true when coming explicitly
via this label. Moving the label down preserves the fall-through
case while avoiding testing an always false condition.

Changes from v1:
- Add a comment explaining that `buf_rx` does not require cleanup
- Use a unique cleanup path for the function by setting `errno` before
  jumping to the cleanup block.

  tcg: Remove unreachable code
  tcg: Make the cleanup-on-error path unique
