Fix memory leak in tpm_binary_bios_measurements_open()
The same problem that was fixed for tpm_ascii_bios_measurements_open() in commit 178554ae75739e91dc4d7c3e42a3db95448cc5bf also occurs in tpm_binary_bios measurements(). Thanks for noticing this Satyam! I tested the attached patch to fix tpm_binary_bios_measurments as well.
