[PATCH AUTOSEL 6.1 28/28] smb3: clarify mount warning

[Sasha Levin <sashal@kernel.org>]

From: Steve French <stfrench@microsoft.com>

[ Upstream commit a5cc98eba2592d6e3c5a4351319595ddde2a5901 ]

When a user tries to use the "sec=krb5p" mount parameter to encrypt
data on connection to a server (when authenticating with Kerberos), we
indicate that it is not supported, but do not note the equivalent
recommended mount parameter ("sec=krb5,seal") which turns on encryption
for that mount (and uses Kerberos for auth).  Update the warning message.
