[PATCH for-8.1 08/17] target/riscv/cpu.c: avoid set_misa() in validate_set_extensions()

[Daniel Henrique Barboza]

set_misa() will be tuned up to do more than it's already doing and it
will be redundant to what riscv_cpu_validate_set_extensions() does.

Note that we don't ever change env->misa_mlx in this function, so
set_misa() can be replaced by just assigning env->misa_ext and
env->misa_ext_mask to 'ext'.
