Subject: [PATCH] perf script: Allow --time with --reltime

From: Andi Kleen <ak@...ux.intel.com>

The original --reltime patch forbid --time with --reltime.

But it turns out --time doesn't really care about --reltime, because
the relative time is only used at final output, while
the time filtering always works earlier on absolute time.

So just remove the check and allow combining the two options.

Fixes: 90b10f47c0ee ("perf script: Support relative time")
