USB: musb: fix compiling warning with min() macro

Current musb gadget dma code produces the warning:
drivers/usb/musb/musb_gadget.c: In function 'txstate':
drivers/usb/musb/musb_gadget.c:312: warning: comparison of distinct
                                             pointer types lacks a cast

So switch to min_t(size_t, ...).
