qmp: Don't use error_is_set() to suppress additional errors

Using error_is_set(errp) that way can sweep programming errors under
the carpet when we get called incorrectly with an error set.

encrypted_bdrv_it() does it, because there's no way to make
bdrv_iterate() break its loop.  Actually safe, because qmp_cont()
clears the error before the loop.  Clean it up anyway: replace
bdrv_iterate() by bdrv_next(), break the loop on error.

Replace both occurrences, for consistency.
