WPS: Replace the httpread_debug design with standard debug prints
The debug information from httpread can be helpful in figuring out error cases in general and as such, should be enabled by default. Get rid of the hardcoded httpread_debug value that would require source code changes to enable. Signed-off-by: Jouni Malinen <j@w1.fi>
