pseries/plpks: clear signed update authentication buffer
The PLPKS signed update operation uses an authentication buffer that
contains a password. Freeing this buffer with kfree(), without wiping
the contents, can leave sensitive data in memory.
Use kfree_sensitive() to wipe the buffer when freeing it.
