bugs/core: Pass down the condition string of WARN_ON_ONCE(cond) warnings to __WARN_FLAGS()
Doing this will allow architecture code to store and print out
this information as part of the WARN_ON and BUG_ON facilities.
The format of the string is '[condition]', for example:
WARN_ON_ONCE(idx < 0 && ptr);
Will get the '[idx < 0 && ptr]' string literal passed down as 'cond_str'
in __WARN_FLAGS().
