target/i386/tcg: fix POP to memory in long mode
In long mode, POP to memory will write a full 64-bit value. However,
the call to gen_writeback() in gen_POP will use MO_32 because the
decoding table is incorrect.
The bug was latent until commit aea49fbb01a ("target/i386: use gen_writeback()
within gen_POP()", 2024-06-08), and then became visible because gen_op_st_v
now receives op->ot instead of the "ot" returned by gen_pop_T0.
