lib: sbi_misaligned_ldst: Set GVA if not emulating

Browse Source 
If a particular misaligned load or store cannot be emulated at all, for
the redirected trap, trap.gva is set to 0, but it should be the same as
mstatus[h].GVA of the original trap. Fix this so that if the trap is
destined for HS-mode, hstatus.GVA is then set correctly.
