[Qemu-devel] [PULL 04/19] nbd: Fix nbd_establish_connection()'s return value

[Paolo Bonzini]

From: Max Reitz <mre...@redhat.com>

unix_connect_opts() and inet_connect_opts() do not necessarily set errno
(if at all); therefore, nbd_establish_connection() should not literally
return -errno on error.
