tracing/kprobe: Remove redundant memset in kprobe_perf_func()

Browse Source 
kprobe_perf_func() calls memset(&entry[1], 0, dsize) prior to calling
store_trace_args(). store_trace_args() populates the entry buffer and
handles dynamic data fields.

Remove this redundant memset call to align with kretprobe_perf_func() and
other probe perf functions.
