Peter Zijlstra 7575e5a352 x86/ibt: Avoid duplicate ENDBR in __put_user_nocheck*()
Commit cb855971d7 ("x86/putuser: Provide room for padding") changed
__put_user_nocheck_*() into proper functions but failed to note that
SYM_FUNC_START() already provides ENDBR, rendering the explicit ENDBR
superfluous.
