Maciej S. Szmigiero 855a14e9c2 w1: ds2490: USB transfer buffers need to be DMAable 
commit 61cd1b4cd1 upstream.

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.
