hw/nvram/xlnx-efuse-ctrl: Free XlnxVersalEFuseCtrl[] "pg0-lock" array

Commit 0be6bfa ("qdev: Implement variable length array properties")
added the DEFINE_PROP_ARRAY() macro with the following comment:

  * It is the responsibility of the device deinit code to free the
  * @_arrayfield memory.

Commit 9e4aa1f added:

  DEFINE_PROP_ARRAY("pg0-lock",
                    XlnxVersalEFuseCtrl, extra_pg0_lock_n16,
                    extra_pg0_lock_spec, qdev_prop_uint16, uint16_t),

but forgot to free the 'extra_pg0_lock_spec' array. Do it in the
instance_finalize() handler.
