nspawn: use ERRNO_IS_NEG_NOT_SUPPORTED() at one more place

Follow-up for dc3223919f663b7c8b8d8d1d6072b4487df7709b.
Addresses https://github.com/systemd/systemd/pull/34067#discussion_r1748061156.

Error codes other than ENOSYS may not come here, but if it comes, still
there is nothing we can do here, so let's not log the failure loudly.
