s390/pkey: fix PKEY_TYPE_EP11_AES handling for sysfs attributes
Commit 'fa6999e326fe ("s390/pkey: support CCA and EP11 secure ECC
private keys")' introduced a new PKEY_TYPE_EP11_AES securekey type as
a supplement to the existing PKEY_TYPE_EP11 (which won't work in
environments with session-bound keys). The pkey EP11 securekey
attributes use PKEY_TYPE_EP11_AES (instead of PKEY_TYPE_EP11)
keyblobs, to make the generated keyblobs usable also in environments,
where session-bound keys are required.
There should be no negative impacts to userspace because the internal
structure of the keyblobs is opaque. The increased size of the
generated keyblobs is reflected by the changed size of the attributes.
