HID: asus: do not send keyboard init reports to touchpads

Commit 0919db9f3583 ("HID: asus: always fully initialize devices") added a
loop during asus_probe() to send keyboard feature report initializations
(asus_kbd_init) to all ASUS HID devices.

On ASUS laptops with I2C/HID touchpads (such as the ASUS E200HA), sending
keyboard feature reports (FEATURE_KBD_REPORT_ID) to touchpad endpoints
sends invalid feature requests to touchpad hardware, corrupting probe
state and causing the touchpad to become unresponsive.

Wrap the asus_report_id_init loop in an `if (!drvdata->tp)` check so
keyboard feature initialization only runs for actual keyboards.

Tested on ASUS E200HA (where touchpad functionality is fully restored)
and ASUS VivoBook Flip 14 TP401MA (confirming zero regressions).
