perf probe: Check -v and -q options in the right place
[ Upstream commit 8b269b75551227796c1ddac2dbdb2ba504158c61 ]
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: 5e17b28f1e246b98 ("perf probe: Add --quiet option to suppress output result message")
