Avihai Horon 4f8cf323e8 migration: Fix migration_channel_read_peek() error path 
migration_channel_read_peek() calls qio_channel_readv_full() and handles
both cases of return value == 0 and return value < 0 the same way, by
calling error_setg() with errp. However, if return value < 0, errp is
already set, so calling error_setg() with errp will lead to an assert.

Fix it by handling these cases separately, calling error_setg() with
errp only in return value == 0 case.

Fixes: 6720c2b327 ("migration: check magic value for deciding the mapping of channels")
