[ Upstream commit cba33db3fc4dbf2e54294b0e499d2335a3a00d78 ]
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.
