hw/milkymist-softusb: set buffer in softusb_read_{dmem, pmem} error path
Make sure we set the buffer to something in the softusb_read_{dmem,pmem} error paths, since the caller will use the buffer unconditionally. (Newer gcc is smart enough to spot this and complain about 'may be used uninitialized'.)
