[PATCH 6.0 114/862] ksmbd: fix endless loop when encryption for response fails

[Greg Kroah-Hartman]

From: Namjae Jeon <linkinjeon@xxxxxxxxxx>

commit 360c8ee6fefdb496fffd2c18bb9a96a376a1a804 upstream.

If ->encrypt_resp return error, goto statement cause endless loop.
It send an error response immediately after removing it.
