[PATCH v2] migration: free 'channel' and 'addr' after their use in migration.c

[Het Gala]

'channel' and 'addr' in qmp_migrate() and qmp_migrate_incoming() are
not auto-freed. migrate_uri_parse() allocates memory which is
returned to 'channel', which is leaked because there is no code for
freeing 'channel' or 'addr'.
So, free addr and channel to avoid memory leak. 'addr' does shallow
copying of channel->addr, hence free 'channel' itself and deep free
contents of 'addr'

Fixes: 5994024f ("migration: Implement MigrateChannelList to qmp
migration flow")
