[PATCH v5 15/19] target/riscv/cpu.c: remove priv_ver check from riscv_isa_string_ext() |

riscv_isa_string_ext() is being used by riscv_isa_string(), which is
then used by boards to retrieve the 'riscv,isa' string to be written in
the FDT. All this happens after riscv_cpu_realize(), meaning that we're
already past riscv_cpu_validate_set_extensions() and, more important,
riscv_cpu_disable_priv_spec_isa_exts().
This means that all extensions that needed to be disabled due to
priv_spec mismatch are already disabled. Checking this again during
riscv_isa_string_ext() is unneeded. Remove it.
As a bonus, riscv_isa_string_ext() can now be used with the 'host'
KVM-only CPU type since it doesn't have a env->priv_ver assigned and it
would fail this check for no good reason.
