Michael Ellerman 1157eb37e2 lib: sbi_trap_v_ldst: Redirect unhandled traps ...

When SBI is built with a compiler that doesn't support vector, the
misaligned vector load/store emulation is not built in, the handlers are
just stubs.

Currently the stubs just return 0, causing sbi_trap_emulate_load() to
return without incrementing mepc, meaning the instruction will just
fault again, an infinite loop.

Fix the stubs to use sbi_trap_redirect(), which forwards the trap to the
previous mode, allowing it to be handled there.
