tpm: tpm1_bios_measurements_next should increase position index
If .next function does not change position index,
following .show function will repeat output related
to current position index.
In case of /sys/kernel/security/tpm0/ascii_bios_measurements
and binary_bios_measurements:
1) read after lseek beyound end of file generates whole last line.
2) read after lseek to middle of last line generates
expected end of last line and unexpected whole last line once again.
