Markus Armbruster 96ac971933 multi-process: Fix pci_proxy_dev_realize() error handling 
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

pci_proxy_dev_realize() is wrong that way: it passes @errp to
qio_channel_new_fd() without checking for failure.  If it runs into
another failure, it trips error_setv()'s assertion.

Fix it to check for failure properly.
