Peter Wu 8fbf5f92d2 ltunify: fix do_read failure when receiving unrelated messages ...

When a touchpad event occurs while the device is being queried (e.g.
for features), then do_io (for do_read) would fail because the report
was not of the correct type (0x20 vs 0x11 for example). To fix this,
make do_read retry reads (within the allowed timeout).

Previously the expected report type was hidden in the msg parameter,
make this expected report type more explicit now in a new parameter.
