tracing/probes: Remove redundant bounds check in trace_probe_compare_arg_type()

Browse Source 
In trace_probe_compare_arg_type(), prior to entering the comparison loop,
a->nr_args and b->nr_args are checked for equality. Since the loop
condition is i < a->nr_args, i is guaranteed to be less than b->nr_args
inside the loop.

Remove the redundant (b->nr_args <= i) check.
