rseq: Fix rseq unregistration regression
A logic inversion in rseq_reset_rseq_cpu_node_id() causes the rseq
unregistration to fail when rseq_validate_ro_fields() succeeds rather
than the opposite.
This affects both CONFIG_DEBUG_RSEQ=y and CONFIG_DEBUG_RSEQ=n.
Fixes: 7d5265ffcd8b ("rseq: Validate read-only fields under DEBUG_RSEQ config")
