dramforever 187127fb89 lib: sbi: Fixup tinst for exceptions in sbi_misaligned_*() ...

If there is an exception while emulating a misaligned load/store, fixup
uptrap.tinst before redirecting. Otherwise, HS-mode software may receive
an htinst describing the lbu/sb instruction that faulted during
emulation[1].
