Use clamp() to simplify odm_evm_db_to_percentage().

When this driver will be moved to drivers/net/wireless/realtek/rtlwifi
(if that's the plan?) the odm_evm_db_to_percentage() function could be
replaced by the generic version rtl_evm_db_to_percentage() from
drivers/net/wireless/realtek/rtlwifi/stats.c
