SecurityPkg: Correct data copy in Tpm2NvReadPublic.
SecurityPkg: Correct data copy in Tpm2NvReadPublic.

1) NvPublic.dataSize data should be got from original
receive buffer, instead of returned NvPublic.

2) NvNameSize means the size of NvName without size field.
The original code treats it to be size of NvName with size
field, so the last 2 bytes are missing.

This patch fixed problem.
