winedbg: Extract address from expression for listing source at address.

[Dylan Smith]

This patch will only apply cleanly after applying my previous patch:
winedbg: Fixed listing source of function in file.

Previously the address that was used to find the line number was the
address of the expression value.  This patch extracts that value from
the expression so the correct address is used to get the line number for
the list command.
