Fix a handful of broken guest assert/printf messages, and annotate guest
ucall, printf, and assert helpers with __printf() so that such breakage is
detected by the compiler.

v2:
 - Annotate the relevant helpers. [Maxim]
 - Fix all other warnings (v1 fixed only the MWAIT error message)

v1: https://lore.kernel.org/all/20231107182159.404770-1-seanjc@google.com

Applied rather quickly to kvm-x86 selftests, as I want to get these a few days
of exposure in -next before sending them to Paolo for 6.7-rc5.  I'll happily do
fixups if there is any feedback that needs to be addressed.  Thanks!
