Yang Jihong 59871742b4 perf probe: Check -v and -q options in the right place ...

[ Upstream commit 8b269b7555 ]

Check the -q and -v options first to return earlier on error.

Before:

  # perf probe -q -v test
  probe-definition(0): test
  symbol:test file:(null) line:0 offset:0 return:0 lazy:(null)
  0 arguments
    Error: -v and -q are exclusive.

After:

  # perf probe -q -v test
    Error: -v and -q are exclusive.

Fixes: 5e17b28f1e ("perf probe: Add --quiet option to suppress output result message")
