wlan: fix driver load failure with legacy regulatory code

When driver is compiled without CONFIG_ENABLE_LINUX_REG flag
the function vos_getCurrentCountryCode() is declared and used
but never defined which results in failure to load the driver.
Make sure that the function is not used when using legacy
regulatory code.
