Crypto library fixes for v6.17-rc5

Browse source

Fix a regression caused by my commits that reimplemented the sha1,
 sha256, and sha512 crypto_shash algorithms on top of the library API.
 Specifically, the export_core and import_core methods stopped being
 supported, which broke some hardware offload drivers (such as qat)
 that recently started depending on these for fallback functionality.
 
 Later I'd like to make these drivers just use the library API for
 their fallback. Then these methods won't be needed anymore. But for
 now, this fixes the regression for 6.17.
