[bootstrap-O3,fortran] add a NULL initializer to avoid a warning at -O3

[Alexandre Oliva]

Building with the bootstrap-O3 configuration option fails to compile
fortran/module.c due to an AFAICT false-positive warning about an
uninitialized use of a variable.

This patch adds a dummy initializer to silence it.

Regstrapped on x86_64-linux-gnu and i686-linux-gnu.  OK to install?
