Fix coverity issues CID 1457745...1457752, 1457853, 1457854 

CID 1457854 - keymgmt_lib.c : OVERRUN
CID 1457853 - self_test_kats.c : UNINT
CID 1457752 - fipsprov.c RESOURCE_LEAK (code change in another PR removed this)
CID 1457751 - apps/pkcs12.c CHECKED_RETURN
CID 1457750 - dsa_ossl.c RESOURCE_LEAK (marked as false positive since tmp can not be NULL)
CID 1457749 - apps/nseq.c : CHECKED_RETURN
CID 1457748 - cipher_aes_cbc_hmac_sha.c : SIZEOF_MISMATCH
CID 1457747 - cipher_aes_cbc_hmac_sha.c : SIZEOF_MISMATCH
CID 1457746 - same as 1457752
CID 1457745 - apps/ocsp  : CHECKED_RETURN
