Fixes problem when fs_opendir invoked on fs_dir_t object,
which is already holding information on opened directory,
overwrites references to other memory objects within
the fs_dir_t object causing resource leak.
If fs_opendir is invoked on already used fs_dir_t object,
it will return
-EBUSY.
Note: The change requires that all fs_dir_t objects should be
initialized to 0.

The fs_dir_t_init() function has been added that should be used
for initialization of fs_dir_t structures before passing them
to fs_open and other functions.

The fs_file_t_init() function has been added that should be used
