For automatic module loading (e.g. as it is used with cryptsetup)
an alias "paes" for the paes_s390 kernel module is needed.
Correct the paes_s390 module alias from "aes-all" to "paes".

The ctr mode of protected key aes uses the ctrblk page if the
ctrblk_lock could be acquired. If the protected key has to be
reestablished and this operation fails the unlock for the
ctrblk_lock is missing. Add it.

This patch introduces a new in-kernel-crypto blockcipher
called 'paes' which implements AES with protected keys.
The paes blockcipher can be used similar to the aes
blockcipher but uses secure key material to derive the
working protected key and so offers an encryption
implementation where never a clear key value is exposed
in memory.
The paes module is only available for the s390 platform
providing a minimal hardware support of CPACF enabled
with at least MSA level 3. Upon module initialization
these requirements are checked.
Includes additional contribution from Harald Freudenberger.
