bpf: Zero index arg error string for dynptr and iter
[ Upstream commit bd74e238ae6944b462f57ce8752440a011ba4530 ]
Andrii spotted that process_dynptr_func's rejection of incorrect
argument register type will print an error string where argument numbers
are not zero-indexed, unlike elsewhere in the verifier. Fix this by
subtracting 1 from regno. The same scenario exists for iterator
messages. Fix selftest error strings that match on the exact argument
number while we're at it to ensure clean bisection.
