  hcrypto PKCS#11 backend: don't leak sessions on digest reinit

Clients of the EVP API can reinitialize message digest contexts
without destroying them. The PKCS#11 backend assumed they were
only used once, and was leaking session handles upon reinitialization.
This fix disposes of any existing PKCS#11 message digest context
in the initialization method.
