fs_dir_handle is only used by callees of efi_check_boot_dt_boot(). So 
the global variable is not an option for me because the risk is not 
worth it (it is easy to misuse a global variable).
Instead, I think fs_dir_handle should be an argument of 
allocate_module_file() and propagated up to the first call in 
efi_check_dt_boot().
