Subject: [PATCH] Fix crypto api init for 3.6.4-rt10

Fix crypto api for 3.6.4-rt10 (broken only in realtime patchset)

In peterz-srcu-crypto-chain.patch the blocking notifier is changed
to srcu notifier and added initialization to module init fucntion.

Later, in crypto-make-core-static-and-init-scru-early.patch, is that
initialization added also to core_initcall().

This patch removes crypto_chain init from algapi initialization,
because this function is called later and already initialized
cryptomgr notifier is lost.

This cause a failure in initialization of larval algorithms,
like e.g. cbc(aes).
