Silecne bogus -Wmaybe-uninitialized warning

[Jan Hubicka]

Hi,
this patch silences -Wmaybe-uninitialized warning when GCC is built
with -finline-functions (which I am working to make part of -O2).

Bootstrapped/regtested x86_64-linux, comitted as obvious.

	* module.c (load_commons): Initialize flags to 0 to silecne
	-Wmaybe-uninitialized warning.
	(read_module): Likewise for n and comp_name.
