[PATCH 2/2] smb/server: fix memory leak in ksmbd_login_user()

From: ZhangGuoDong <[email protected]>

ksmbd_ipc_login_request_ext() returns an independently allocated
response. ksmbd_alloc_user() copies the supplementary group IDs from
the response, but ksmbd_login_user() does not release it.

Free the extended response after ksmbd_alloc_user() has finished with
it.
