Subject: [PATCH] ksmbd: Remove unused functions

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

ksmbd_rpc_rap() was added in 2021 as part of
commit 0626e6641f6b ("cifsd: add server handler for central processing and
tranport layers")

ksmbd_vfs_posix_lock_wait_timeout() was added in 2021 as part of
commit f44158485826 ("cifsd: add file operations")

both have remained unused.

Remove them.

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