qemu-option: qemu_opts_create(): use error_set()
This commit converts qemu_opts_create() from qerror_report() to
error_set().
Currently, most calls to qemu_opts_create() can't fail, so most
callers don't need any changes.
The two cases where code checks for qemu_opts_create() erros are:
1. Initialization code in vl.c. All of them print their own
error messages directly to stderr, no need to pass the Error
object
2. The functions opts_parse(), qemu_opts_from_qdict() and
qemu_chr_parse_compat() make use of the error information and
they can be called from HMP or QMP. In this case, to allow for
incremental conversion, we propagate the error up using
qerror_report_err(), which keeps the QError semantics
