[ Upstream commit 2c0f0f3639562d6e38ee9705303c6457c4936eac ]

Commit 013c1667cf78 ("kallsyms: refactor
{,module_}kallsyms_on_each_symbol") replaced the return inside the
nested loop with a break, changing the semantics of the function: the
break only exits the innermost loop, so the code continues iterating the
symbols of the next module instead of exiting.

Fixes: 013c1667cf78 ("kallsyms: refactor {,module_}kallsyms_on_each_symbol")
