asus-laptop: Fix an uninitialized variable
The value returned by acpi_evaluate_integer() is not checked,
but the result is not always successful, so it is necessary to
add a check of the returned value.
If the result remains negative during three iterations of the loop,
then the uninitialized variable 'val' will be used in the clamp_val()
macro, so it must be initialized with the current value of the 'curr'
variable.
In this case, the algorithm should be less noisy.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
