nbd: don't update block size after device is started
[ Upstream commit b40813ddcd6bf9f01d020804e4cb8febc480b9e4 ]
Mounted NBD device can be resized, one use case is rbd-nbd.
Fix the issue by setting up default block size, then not touch it
in nbd_size_update() any more. This kind of usage is aligned with loop
which has same use case too.
