lib: sbi: Rework and split sbi_misaligned(_v)_tinst_fixup
The load/store address offset between the uptrap and the orig_trap
can be derived by orig_trap->tval - uptrap->tval, thus refactor
the function prototype for simplicity.
For vector load, sbi_misaligned_v_tinst_fixup is introduced. There's
no transformed instruction for vector load/store, so null out tinst
if the fault is not a guest-page fault.
