[PATCH v8 0/4] delete created files when block_crypto_co_create_opts_luks fails

[Daniel Henrique Barboza <danielhb413@gmail.com>]

changes from previous version 7 [1], all suggested by Kevin Wolf:

- patch 1:
    * removed function comment of raw_co_delete_file;
    * removed 'done' label from raw_co_delete_file;
    * removed 'local' remark from bdrv_co_delete_file comment. The comment
      is now single-lined;
    * added missing space in the commit msg;
- patch 2:
    * ditched bdrv_delete_co_entry and bdrv_delete_file, now it's a single
      coroutine_fn bdrv_co_delete_file;
    * BlockDriverState != NULL dropped - the caller will need to ensure it
      is not null;
    * changed the error message of '!bs->drv' condition;
    * s/delete/deletion in the error message of !bs->drv->bdrv_co_delete_file;
    * 'out' label removed - function will return immediately on error;
- patch 3:
    * check for (ret && bs);
    * drop the ENOENT verification;
    * do not prepend the filename in the error message;
    * removed an extra blank line.
