[PULL 18/31] block/export: fix blk_size double byteswap

[Kevin Wolf]

From: Stefan Hajnoczi <stefanha@redhat.com>

The config->blk_size field is little-endian. Use the native-endian
blk_size variable to avoid double byteswapping.

Fixes: 11f60f7eaee2630dd6fa0c3a8c49f792e46c4cf1 ("block/export: make 
vhost-user-blk config space little-endian")
