6e22f23831 tpm: save almost 8KB stack space 
The largest possible PTM response is only 16 bytes. Size the output
buffer correctly.

In the socket read function, rely on the caller to provide a
sufficiently large buffer. That eliminates another large stack variable.

In total this saves almost 8KB stack space.
