NBD: set uninitialized devices to size 0
This fixes errors with utilities (such as LVM's vgscan) that try to scan all
devices. Previously this would generate read errors when uninitialized nbd
devices were scanned:
# vgscan
Reading all physical volumes. This may take a while...
/dev/nbd0: read failed after 0 of 1024 at 0: Input/output error
/dev/nbd0: read failed after 0 of 1024 at 509804544: Input/output error
/dev/nbd0: read failed after 0 of 2048 at 0: Input/output error
/dev/nbd1: read failed after 0 of 1024 at 509804544: Input/output error
/dev/nbd1: read failed after 0 of 2048 at 0: Input/output error
From now on, uninitialized nbd devices will have size zero, which
prevents these errors.
