[PATCH] platform/x86: hp-wmi: fix power limit failure for Victus 15-fb0xxx (8A3D)

[Sourav Nayak <nonameblank007@gmail.com>]

Victus 15-fb0xxx (8A3D) does not support 0x29 query,
Casuing severe CPU power limit after disconnect/connect of charger.

- Fix this regression by restoring user selected profile,
- It matches behaviour written in omen_power_source_event.

Error output:
[ +14.861905] hp_wmi: query 0x29 returned error 0x29
[  +0.000036] hp_wmi: Failed to actualize power limits: 41
