[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.
