Update _log function to drop any traces when log is yet initialized: vsnprintf is no more executed in this case.
This patch allows to reduce the cost for the dropped early debug trace.

How early are you expecting this function to get called? AFAIK this will only return true before board_init_f_init_reserve. Shouldn't functions that early just not call log in the first place?
Heinrich may have some thoughts here.
I think we will end up using log very early, since it is sort-of the replacement for printf() and debug().
