The code tends to include errno into error messages after
tpm_util_test_tpmdev() and tpm_emulator_ctrlcmd() calls.
Both has error paths, where errno is not set, examples:
tpm_emulator_ctrlcmd()
qemu_chr_fe_write_all()
qemu_chr_write()
replay_char_write_event_load()
...
*res = replay_get_dword();
...
tpm_util_test_tpmdev()
tpm_util_test()
tpm_util_request()
...
if (n != requestlen) {
return -EFAULT;
}
...
Both doesn't document that they set errno.
Let's drop these explicit usage of errno. If we need this information,
it should be added to errp deeper in the stack.
