log: fix tag comparison in esp_log_level_set

Browse source 
This is a fix for the esp_log_level_set function. The problem is when this
function is called but NOT withe the same 'c' string constant that the LOG*
calls used in each module, the cache check doesn't match, so the cached
entry won't get updated. There's no point in optimizing this function
anyway because it is only called rarely.
