ACPI: button: Drop redundant variable from acpi_button_probe()

Local char pointer called "name" in acpi_button_probe() is redundant
because its value can be assigned directly to input->name and the
latter can be used in the only other place where "name" is read, so
get rid of it.

No intentional functional impact.
