[CRYPTO] api: Added cra_init/cra_exit
This patch adds the hooks cra_init/cra_exit which are called during a tfm's construction and destruction respectively. This will be used by the instances to allocate child tfm's. For now this lets us get rid of the coa_init/coa_exit functions which are used for exactly that purpose (unlike the dia_init function which is called for each transaction). In fact the coa_exit path is currently buggy as it may get called twice when an error is encountered during initialisation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
