Karsten Wiese 0f6d12e144 rtl8188eu: Fix "fix some UBSAN and kmalloc warnings" 
This fixes
commit 4a73c76f02
Author: Larry Finger <Larry.Finger@lwfinger.net>
Date:   Mon May 10 10:25:47 2021 -0500

    rtl8188eu: fix some UBSAN and kmalloc warnings

For LINUX_VERSION_CODE < KERNEL_VERSION(5, 8, 0).

The function argument 'upd' only exists, if
LINUX_VERSION_CODE >= KERNEL_VERSION(5, 8, 0),
hence move the 'if' block reading 'upd' inside the
'#if (LINUX_VERSION_CODE >= KERNEL_VERSION(5, 8, 0))' macro guard.
