Subject: [PATCH net-next 1/5] qed: Remove unused qed_memset_*ctx functions

From: "Dr. David Alan Gilbert" <linux@...blig.org>

qed_memset_session_ctx() and qed_memset_task_ctx() were added in 2017
as part of
commit da09091732ae ("qed*: Utilize FW 8.33.1.0")

but have not been used.

Remove them.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
