target/i386: clear CPU_INTERRUPT_SIPI for all accelerators

Browse source 
Similar to what commit df32e5c5 did for TCG; fixes boot with multiple
processors on WHPX and probably more accelerators

Fixes: df32e5c568 ("i386/cpu: Prevent delivering SIPI during SMM in TCG mode", 2025-10-14)
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/3178
