win32-glob: fix resource leak on bad pattern
win32-glob: fix resource leak on bad pattern

Open the HANDLE hfindfile later, after the checks of pattern, flags,
unused, pglob and length of file name. This avoids a possible return
from function glob() without FindClose(hfindfile).

- Fixes the following Cppcheck errors:
  [src/win32-glob.c:80]
    (error) Resource leak: hfindfile [resourceLeak]
  [src/win32-glob.c:88]
    (error) Resource leak: hfindfile [resourceLeak]
