[flang] Fix race condition in runtime

Authored by klausler on May 5 2021, 11:28 AM.



The code that initializes the default units 5 & 6 had
a race condition that would allow threads access to the
unit map before it had been populated.

Also add some missing calls to va_end() that will never
be called (they're in program abort situations) but might
elicit warnings if absent.
