[PATCH 1/3] um: Use err consistently in userspace()

[Tiwei Bie <tiwei.bie@linux.dev>]

From: Tiwei Bie <tiwei.btw@antgroup.com>

Avoid declaring a new variable 'ret' inside the 'if (using_seccomp)'
block, as the existing 'err' variable declared at the top of the
function already serves the same purpose.
