Subject: crypto: pcrypt - Do not clear MAY_SLEEP flag in original request

crypto: pcrypt - Do not clear MAY_SLEEP flag in original request

commit e8d998264bffade3cfe0536559f712ab9058d654 upstream.

We should not be modifying the original request's MAY_SLEEP flag
upon completion.  It makes no sense to do so anyway.
