[PATCH 0/1] MR978: kernelbase: Fix uninitialized return value in GetModuleHandleA().

[eric pouech (＠epo)]

GCC (MingW) 12.2 rightfully warns with:
/home/eric/work/wine/dlls/kernelbase/loader.c: In function 'GetModuleHandleA':
/home/eric/work/wine/dlls/kernelbase/loader.c:332:12: warning: 'ret' may be used uninitialized [-Wmaybe-uninitialized]
  332 |     return ret;
      |            ^~~
/home/eric/work/wine/dlls/kernelbase/loader.c:329:13: note: 'ret' declared here
  329 |     HMODULE ret;
      |             ^~~
So set module to NULL on all error codepaths in GetModuleHandleExA().
