Fix memory leak in tpm_binary_bios_measurements_open()

Browse Source 
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.
