[Qemu-devel] [PATCH v4 29/38] tpm: Clean up error reporting in tpm_init_tpmdev() |

Calling error_report() in a function that takes an Error ** argument
is suspicious. tpm_init_tpmdev() does that, and then fails without
setting an error. Its caller main(), via tpm_init() and
qemu_opts_foreach(), is fine with it, but clean it up anyway.
