Commit 2f2bd7cbd1d1 ("hid: lenovo: Resend all settings on reset_resume
for compact keyboards") introduced a regression for ThinkPad TrackPoint
Keyboard II by removing the conditional check for enabling F7/9/11 mode
needed for compact keyboards only. As a result, the non-compact
keyboards can no longer toggle Fn-lock via Fn+Esc, although it can be
controlled via sysfs knob that directly sends raw commands.

This patch restores the previous conditional check without any
additions.
