The second check on pcr_map in sandbox_tpm2_xfer() is wrong. It should
check for pcr_map not being empty. Instead, it is a pure copy/paste of
the first check which is redundant.
This has been found thanks to a Coverity Scan report:
CID 183370: Memory - illegal accesses (UNINIT)
Using uninitialized value "pcr_index".
put_unaligned_be32(tpm->pcr_extensions[pcr_index], recv);
This is because pcr_index is initialized only if the user input is
correct, ie. at least one valid bit is set in pcr_map.
Fix the second check and also initialize pcr_index to 0 (which is
harmless in case of error) to make Coverity Scan happy.
