target/arm/ptw.c: Account for FEAT_RME when applying {N}SW, SA bits 

In get_phys_addr_twostage() the code that applies the effects of
VSTCR.{SA,SW} and VTCR.{NSA,NSW} only updates result->f.attrs.secure.
Now we also have f.attrs.space for FEAT_RME, we need to keep the two
in sync.

These bits only have an effect for Secure space translations, not
for Root, so use the input in_space field to determine whether to
apply them rather than the input is_secure. This doesn't actually
make a difference because Root translations are never two-stage,
but it's a little clearer.
