graycode, morse, pwm, usb_request, wiegand: cope with absent sample rate
Improve robustness of some more protocol decoders. Few of them never
checked for the availability of a sample rate in the first place, others
checked for the presence of a spec but would not cope with a value of 0.
Some checked the value only after processing it, which could result in
runtime errors.
This change is motivated by bug #1118.
