[PATCH 19/21] qapi: Inline and remove QERR_QGA_COMMAND_FAILED definition

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Address the comment added in commit 4629ed1e98
("qerror: Finally unused, clean up"), from 2015:

  /*
   * These macros will go away, please don't use
   * in new code, and do not add new ones!
   */

Mechanical transformation using the following
coccinelle semantic patch:

    @match exists@
    expression errp;
    expression errmsg;
    @@
         error_setg(errp, QERR_QGA_COMMAND_FAILED, errmsg);

    @script:python strformat depends on match@
    errmsg << match.errmsg;
    fixedfmt; // new var
    @@
    # Format skipping '"'.
    fixedfmt = f'"Guest agent command failed, error was \'{errmsg[1:-1]}\'"'
    coccinelle.fixedfmt = cocci.make_ident(fixedfmt)

    @replace@
    expression match.errp;
    expression match.errmsg;
    identifier strformat.fixedfmt;
    @@
    -    error_setg(errp, QERR_QGA_COMMAND_FAILED, errmsg);
    +    error_setg(errp, fixedfmt);

then manually removing the definition in include/qapi/qmp/qerror.h.
