Subject: [PATCH] nbd: Use set_blocksize() to set device blocksize
Git-commit: c8a83a6b54d0ca078de036aafb3f6af58c1dc5eb
Patch-mainline: v5.0-rc3
References: bsc#1124984

NBD can update block device block size implicitely through
bd_set_size(). Make it explicitely set blocksize with set_blocksize() as
this behavior of bd_set_size() is going away.
