asus_acpi: fix a memory leak in asus_hotk_get_info()
In the case of no match ( hotk->model == END_MODEL ), model sholud be
kfreed before return AE_OK.
This patch includes below fixes:
1. adds a missing kfree(model) before return AE_OK.
2. asus_hotk_get_info should return int, thus return 0 instead of AE_OK.
