Revert "Fix 'pdata.found == 1' assert in handle_thunk on ARM platforms"

This reverts commit 7cc90da32ea55f378e871d11da64d7d30872b078.
Dont assert in handle_thunk on ARM when thunk fails. This will lead to slow performance but avoids but its a better outcome than killing the application. Leaving the g_print to let the user know something is wrong. A more premanent solution is needed by the JIT maintainers.
