target/riscv: Fix update of hstatus.SPVP
When trapping from virt into HS mode, hstatus.SPVP was set to
the value of sstatus.SPP, as according to the specification both
flags should be set to the same value.
However, the assignment of SPVP takes place before SPP itself is
updated, which results in SPVP having an outdated value.
