x86/entry/64: Drop idtentry's manual stack switch for user entries
For non-paranoid entries, idtentry knows how to switch from the
kernel stack to the user stack, as does error_entry. This results
in pointless duplication and code bloat. Make idtentry stop
thinking about stacks for non-paranoid entries.
This reduces text size by 5377 bytes.
This goes back to the following commit:
7f2590a110b8 ("x86/entry/64: Use a per-CPU trampoline stack for IDT entries")
