target/arm/hvf: sign extend the data for a load operation when SSE=1
In the syndrome value for a data abort, bit 21 is SSE, which is
set to indicate that the abort was on a sign-extending load. When
we handle the data abort from the guest via address_space_read(),
we forgot to handle this and so would return the wrong value if
the guest did a sign-extending load to an MMIO region. Add the
sign-extension of the returned data.
