usb: gadget: f_mass_storage: remove unnecessary open check
The fsg_lun_is_open() test can be eliminated and the code merged with the preceding conditional, because the LUN won't be open if cfg->filename wasn't set. Similarly, the error_lun label will never be reached with an open lun (non-null filp) so remove the unnecessary fsg_lun_close() call.
