Fix --line to check valid C-style function name and returns
a semantic error if it is not.
For example, previously, --line doesn't support lazy pattern
but it doesn't recognized as a semantic error.
----
# perf probe -L 'func;return*:0-10'
Specified source line is not found.
Error: Failed to show lines.
----
With this patch, it is correctly handled as a semantic error.
----
# perf probe -L 'func;return*:0-10'
Semantic error :'func;return*' is not a valid function name.
