x86/asm/entry/64: Update comments about stack frames
Tweak a few outdated comments that were obsoleted by recent changes
to syscall entry code:
- we no longer have a "partial stack frame" on
entry, ever.
- explain the syscall entry usage of old_rsp.
Partially based on a (split out of) patch from Denys Vlasenko.
