It is unable to read the entry when it is the only one in
binary_bios_measurements:
00000000 00 00 00 00 08 00 00 00 c4 2f ed ad 26 82 00 cb
00000010 1d 15 f9 78 41 c3 44 e7 9d ae 33 20 00 00 00 00
00000020
This is obviously a firmware problem on my linux machine:
Manufacturer: Inspur
Product Name: SA5212M4
Version: 01
However, binary_bios_measurements should return it any way,
rather than nothing, after all its content is completely
valid.
Fixes: 55a82ab318 ("tpm: add bios measurement log")

The responsibility of tpm1_bios_measurements_start() is to walk over the
first *pos measurements, ensuring the skipped and to-be-read
measurements are not out-of-boundary.
This commit simplifies the loop by employing a do-while loop with
the necessary sanity check.
