RISC-V: Fix bug of AVL propagation PASS

A run FAIL suddenly shows up today to me:
FAIL: gcc.target/riscv/rvv/autovec/gather-scatter/mask_gather_load_run-11.c execution test

that I didn't have before.

After investigation, I realize that there is a bug in AVL propagtion PASS.

gcc/ChangeLog:

* config/riscv/riscv-avlprop.cc
(pass_avlprop::get_vlmax_ta_preferred_avl): Don't allow
non-real insn AVL propation.
