hw/smbios: Fix leaked fd in save_opt_one() error path

Browse Source 
Fix the following Coverity issue (RESOURCE_LEAK):

  CID 1432879: Resource leak

    Handle variable fd going out of scope leaks the handle.

Replace a close() call by qemu_close() since the handle is
opened with qemu_open().

Fixes: bb99f4772f5 ("hw/smbios: support loading OEM strings values from a file")
