[PATCH] ntdll: Avoid repeated FIXME messages in NtQueryInformationThread

[qaisjp at gmail.com]

From: Qais Patankar <qaisjp at gmail.com>

This complements commit 01c2af446a325bcb5535ee1665a4abc7fa99c2fd which
was intended to make the messages from #36821 less noisy.

The messages now made less noisy are of this pattern:
    003f:fixme:thread:NtQueryInformationThread info class 22 not supported yet
