tpm: Fix display of data in pubek sysfs entry
This patch fixes the TPM's pubek sysfs entry that is accessible as long
as the TPM doesn't have an owner. It was necessary to shift the access to the
data by -10 -- the first byte immediately follows the 10 byte header. The
line
data = tpm_cmd.params.readpubek_out_buffer;
sets it at the offset '10' in the packet, so we can read the data array
starting at offset '0'.
