usb: gadget: storage_common: Remove FSG specific definitions.

Since g_file_storage has been removed, this commit removes code from
the storage_common.c file which has been used by file_storage.c only
(and not by f_mass_storage.c).

- * are redundant since composite.h is included any way.

- * One could check whether those macros are already defined (which
- * would indicate composite.h had been included) or not (which would
- * indicate we were in FSG) but this is not done because a warning is
- * desired if definitions here differ from the ones in composite.h.
- *
- * We want the definitions to match and be the same in File Storage
- * Gadget as well as Mass Storage Function (and so composite gadgets
- * using MSF).  If someone changes them in composite.h it will produce
- * a warning in this file when building MSF.
