lib/tpm2_marshaling: fix in correct buffer space semantics

marshal_blob() was setting an unsigned size (size_t) to a value
of -1 when an error is determined. This is wrong for the current
implementation of the code because the code assumes the buffer
space gets set to 0. Setting an unsigned value to -1 effectively
tells the library the buffer has unlimited amount of space.
