crypto: pcrypt - restore callback for non-parallel fallback

In the Linux kernel, the following vulnerability has been resolved:

crypto: pcrypt - restore callback for non-parallel fallback

pcrypt installs pcrypt_aead_done() on the child AEAD request before
trying to submit it through padata.  If padata_do_parallel() returns
-EBUSY, pcrypt falls back to calling the child AEAD directly.

That fallback must not keep the padata completion callback.  Otherwise
an asynchronous completion runs pcrypt_aead_done() even though the
request was never enrolled in padata.

Restore the original request callback and callback data before calling
the child AEAD directly.  This keeps the fallback path aligned with a
direct AEAD request while leaving the parallel path unchanged.
