ds2490 driver was doing USB transfers from / to buffers on a stack. This is not permitted and made the driver non-working with vmapped stacks. Since all these transfers are done under the same bus_mutex lock we can simply use shared buffers in a device private structure for two most common of them. While we are at it, let's also fix a comparison between int and size_t in ds9490r_search() which made the driver spin in this function if state register get requests were failing.
