tpm_emulator: print error on error-ignore path

Browse Source 
Commit 3469a56fa3 introduced errp passthrough for many
errors in the file. But in this specific case in
tpm_emulator_get_buffer_size(), it simply used errp=NULL, so we lose
printed error. Let's bring it back

Note also, that 3469a56fa3 was fixing another commit,
42e556fa3f "backends/tpm: Propagate vTPM error on migration failure"
and didn't mention it.

Fixes: 3469a56fa3 "tmp_emulator: improve and fix use of errp"
