The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
qauthz_list_file_complete() is wrong that way: it passes @errp to
qauthz_list_file_complete() without checking for failure. If it runs
into another failure, it trips error_setv()'s assertion. Reproducer:
$ qemu-system-x86_64 -nodefaults -S -display none -object authz-list-file,id=authz0,filename=
qemu-system-x86_64: ../util/error.c:59: error_setv: Assertion `*errp == NULL' failed.
Aborted (core dumped)
Fix it to check for failure.
