Ignore memory limits while logging

Browse Source 
Otherwise there can be pretty noisy messages, like here [1]:

    Cannot add message to the log: Code: 241. DB::Exception: Memory limit (for user) exceeded: would use 42.02 MiB (attempt to allocate chunk of 2101278 bytes), maximum: 4.77 MiB. OvercommitTracker decision: Waiting timeout for memory to be freed is reached. (MEMORY_LIMIT_EXCEEDED), Stack trace (when copying this message, always include the lines below):

And it should be okay to ignore server limits too, since it always
better to have a proper log message in a proper place, not stderr which
does not inspected usually.
