s390/paes: fix PKEY_TYPE_EP11_AES handling for secure keyblobs

Browse source 
[ Upstream commit cba33db3fc ]

Commit 'fa6999e326fe ("s390/pkey: support CCA and EP11 secure ECC
private keys")' introduced PKEY_TYPE_EP11_AES securekey blobs as a
supplement to the PKEY_TYPE_EP11 (which won't work in environments
with session-bound keys). This new keyblobs has a different maximum
size, so fix paes crypto module to accept also these larger keyblobs.
