Old single touch Tablet PCs do not have touch_max set at wacom_features. Since touch device at lease supports one finger, assign touch_max to 1 when touch usage is defined in its HID Descriptor and touch_max is not pre-defined.

Since read and write share a buffer, it needs to be set back up before writing though. Issue is not seen a lot because 1) it doesn't need to retry for a lot of tablets and 2) a lot of failures that need a retry are from an -ETIMEDOUT and hopefully buffer is not touched in this case. At least one user has shown logs with buffer being modified during -ETIMEDOUT case with linux 3.7 kernel.
