[PATCH] markup_oops: Use modinfo to avoid confusion with underscored module names

[Ozan ÃaÄlayan]

When EIP is at a module having an underscore in its name, the current
code fails to find it because the module filenames has '-' instead of
'_'.

Use modinfo to correctly get the full path to the module.

This is just a trivial patch to pinpoint the problem. Usage of modinfo is faster than
searching through the filesystem but may not be desirable as it brings a dependency
to module-init-tools. Replacing underscore occurences by '-' can be another solution.
