crypto: octeontx2 - Fix cptvf driver cleanup

Browse Source 
[ Upstream commit c480a421a4faf693c38e60b0fe6e554c9a3fee02 ]

This patch fixes following cleanup issues:
 - Missing instruction queue free on cleanup. This
   will lead to memory leak.
 - lfs->lfs_num is set to zero before cleanup, which
   will lead to improper cleanup.
