usb: f_ccid: Assign descriptors only in function bind 



Currently we assign the FS, HS and SS descriptors in bind_config
unconditionally. If the max supported speed is high, then bind
function does not allocate SS descriptors but the unbind function
calls usb_free_all_descriptors which results in slab error since
the SS descriptors exist anyway.
Fix this by assigning any function descriptors during bind only.
