usb: gadget: f_fs: resurect usb_functionfs_descs_head structure

Even though usb_functionfs_descs_head structure is now deprecated, it has been used by some user space tools. Its removel in commit [ac8dde1: “Add flags to descriptors block”] was an oversight leading to build breakage for such tools. Bring it back so that old user space tools can still be build without problems on newer kernel versions.
