apm-emulation: hide an unused variable

Browse Source 
The driver_version variable is only used inside of an #ifdef block, which
leads to a W=1 warning:

drivers/char/apm-emulation.c:144:19: error: 'driver_version' defined but not used [-Werror=unused-const-variable=]

Move this into the function using it.
