[PATCH 5.14 033/168] net: qrtr: revert check in qrtr_endpoint_post()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit d2cabd2dc8da78faf9b690ea521d03776686c9fe upstream.

I tried to make this check stricter as a hardenning measure but it broke
audo and wifi on these devices so revert it.
