profile: prevent a crash when line number is unknown

For some unknown reason, `self.lineno` can be None. The previous code crashed in
such case, we now ignore the case, as we do for other error in this function.

We also fallback to using `-1` in the output when this lack of line number
makes it to the display code.

The reason of unknown line-numbers is… unknown.
