### Description

In the Linux kernel, the following vulnerability has been resolved:crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSYSince commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask forPADATA_RESET"), the pcrypt encryption and decryption operations return-EAGAIN when the CPU goes online or offline. In alg_test(), a WARN isgenerated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns-EAGAIN, the unnecessary panic will occur when panic_on_warn set 1.Fix this issue by calling crypto layer directly without parallelizationin that case.
