[PATCH v2 01/15] target/arm/ptw: Don't set fi->s1ptw for UnsuppAtomicUpdate fault

[Peter Maydell]

For an Unsupported Atomic Update fault where the stage 1 translation
table descriptor update can't be done because it's to an unsupported
memory type, this is a stage 1 abort (per the Arm ARM R_VSXXT).  This
means we should not set fi->s1ptw, because this will cause the code
in the get_phys_addr_lpae() error-exit path to mark it as stage 2.
