target-i386: mmu: fix handling of noncanonical virtual addresses
mmu_translate is supposed to return an error code for page faults; it is
not able to handle other exceptions. The #GP case for noncanonical
virtual addresses is not handled correctly, and incorrectly raised as
a page fault with error code 1. Since it cannot happen for nested
page tables, move it directly to handle_mmu_fault, even before the
invocation of mmu_translate.
Fixes: #676
Fixes: 661ff4879e ("target/i386: extract mmu_translate", 2021-05-11)
