cfg_cmd is initialized to zero and this value is never read, instead
it is over-written in the start of a do-while loop. Remove the
redundant initialization. Cleans up clang warning:
drivers/net/wireless/realtek/rtlwifi/core.c:1750:22: warning: Value
stored to 'cfg_cmd' during its initialization is never read
