Subject: [PATCH v2 0/4] riscv: modules: Fix module loading error handling

When modules are loaded while there is not ample allocatable memory,
there was previously not proper error handling. This series fixes a
use-after-free error and a different issue that caused a non graceful
exit after memory was not properly allocated.
