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Tweak a few outdated comments that were obsoleted by recent changes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.
