usb-storage: Use const to reduce object data size

Make structs const to reduce data size ~20KB.

Change function arguments and prototypes as necessary to compile.

$ size (x86-64 defconfig pre)
   text    data     bss     dec     hex filename

$ size (x86-64 defconfig post)
   text    data     bss     dec     hex filename
