dmaengine: dmatest: Allow negative timeout value to specify infinite wait

Browse source 
The dmatest module parameter 'timeout' is documented as accepting a -1 to mean
"infinite timeout". However, an infinite timeout is not advised, nor possible
since the module parameter is an unsigned int, which won't accept a negative
value. Change the parameter type to be signed integer.
