target/riscv: fix error on exit with uninitialized target 

riscv_deinit_target() tries to get_target_type() even
if the examination failed or was not called at all.
dtm_version is not known and an annoying error is printed:

  Error: [riscv.cpu.0] Unsupported DTM version: -1
  Error: [riscv.cpu.0] Could not identify target type.

Avoid calling get_target_type() if dtm_version is
DTM_DTMCS_VERSION_UNKNOWN.
