spapr-tpm-proxy: Drop misleading check
Coverity is reporting in CID
1405304 that tpm_execute() may pass a NULL
tpm_proxy->host_path pointer to open(). This is based on the fact that
h_tpm_comm() does a NULL check on tpm_proxy->host_path and then passes
tpm_proxy to tpm_execute().
The check in h_tpm_comm() is abusive actually since a spapr-proxy-tpm
requires a non NULL host_path property, as checked during realize.
