smbios: buffer overflow when zeroing entry point
A SMBIOS 3 entry point has a different length than an SMBIOS 2.1 entry
point.
Fixes: 70924294f375 ("smbios: Use SMBIOS 3.0 to support an address above 4GB")
Fixes: 1c5f6fa3883d ("smbios: Drop support for SMBIOS2 tables")
Addresses-Coverity-ID: 477212 ("Wrong sizeof argument")
