[PATCH 1/7] hw/i386/sgx: Get rid of qemu_open_old()

For qemu_open_old(), osdep.h said:

> Don't introduce new usage of this function, prefer the following
> qemu_open/qemu_create that take an "Error **errp".

So replace qemu_open_old() with qemu_open(). And considering the SGX
enablement description is useful, convert it into a error message hint.
