lib/mpi: Fix karactx leak in mpi_powm
commit c8ea9fce2baf7b643384f36f29e4194fa40d33a6 upstream.
Sometimes mpi_powm will leak karactx because a memory allocation
failure causes a bail-out that skips the freeing of karactx. This
patch moves the freeing of karactx to the end of the function like
everything else so that it can't be skipped.
