[PULL 11/16] usbredir: avoid queuing hello packet on snapshot restore

[Gerd Hoffmann]

From: Joelle van Dyne <j...@getutm.app>

When launching QEMU with "-loadvm", usbredir_create_parser() should avoid
setting up the hello packet (just as with "-incoming". On the latest version
of libusbredir, usbredirparser_unserialize() will return error if the parser
is not "pristine."
