[Qemu-block] [PATCH v2 2/2] nbd: Tolerate more errors to structured reply request

A server may have a reason to reject a request for structured replies, beyond just not recognizing them as a valid request; similarly, it may have a reason for rejecting a request for a meta context. It doesn't hurt us to continue talking to such a server; otherwise 'qemu-nbd --list' of such a ser

[Qemu-block] [PATCH v2 1/2] nbd: Use g_autofree in a few places

Also, no needs to consider previously calculated permissions, as at this point we already bind all new parents and bdrv_get_cumulative_perm result is enough. So fix the bug by just set permissions by bdrv_get_c
