ACPI: button: Tweak acpi_button_remove()

Browse Source 
Modify acpi_button_remove() to get the ACPI device object pointer
from button->adev instead of retrieving it with the help of the
ACPI_COMPANION() macro to reduce overhead slightly.

While at it, rename the struct acpi_device pointer variable in
acpi_button_remove() to adev.

No intentional functional impact.
