target/i386: Always completely initialize TranslateFault
In get_physical_address, the canonical address check failed to
set TranslateFault.stage2, which resulted in an uninitialized
read from the struct when reporting the fault in x86_cpu_tlb_fill.
Adjust all error paths to use structure assignment so that the
entire struct is always initialized.
