perf arm-spe: Refactor arm_spe_get_events()
In function arm_spe_get_events(), the event packet's 'index' is assigned
as payload length, but the flow is not directive: it firstly gets the
packet length from the return value of arm_spe_get_payload(), the value
includes header length (1) and payload length:
int ret = arm_spe_get_payload(buf, len, packet);
and then reduces header length from packet length, so finally get the
payload length:
packet->index = ret - 1;
To simplify the code, this patch directly assigns payload length to
event packet's index; and at the end it calls arm_spe_get_payload() to
return the payload value.
