Commit c4e34dd99f2e ("x86: simplify load_unaligned_zeropad()
implementation") changes how exceptions around load_unaligned_zeropad()
handled. The kernel now uses the fault_address in fixup_exception() to
verify the address calculations for the load_unaligned_zeropad().
It works fine for #PF, but breaks on #VE since no fault address is
passed down to fixup_exception().
Propagating ve_info.gla down to fixup_exception() resolves the issue.
See commit 1e7769653b06 ("x86/tdx: Handle load_unaligned_zeropad()
page-cross to a shared page") for more context.
