HV: rename append_seed_arg to fill_seed_arg

Browse Source 
Previously append_seed_arg() just do fill in seed arg to dest cmd buffer,
so rename the api name to fill_seed_arg().

Since fill_seed_arg() will be called in SOS VM path only, the param of
bool vm_is_sos is not needed and will be replaced by dest buffer size.

The seed_args[] which used by fill_seed_arg() is pre-defined as all-zero,
so memset() is not needed in fill_seed_arg(), buffer pointer check
and strncpy_s() are not needed also.
