[efi] Check buffer length for packets retrieved via our SNP protocol
We do not currently check the length of the caller's buffer for
received packets. This creates a potential buffer overrun when iPXE
is being used via the SNP or UNDI protocols.
Fix by checking the buffer length and correctly returning the required
length and an EFI_BUFFER_TOO_SMALL error.
