thinkpad_acpi: Remove side effects from vdbg_printk -> no_printk macro
vdbg_printk when not using CONFIG_THINKPAD_ACPI_DEBUG uses
no_printk which produces no logging output but always
evaluates arguments.
Change the macro to surround the no_printk call with
do { if (0) no_printk(...); } while (0)
to avoid the unnecessary argument evaluations.
