xen-blkfront: fix data size for xenbus_gather in blkfront_connect
commit 4352b47ab7918108b389a48d2163c9a4c2aaf139 upstream.
barrier variable is int, not long. This overflow caused another variable
override: "err" (in PV code) and "binfo" (in xenlinux code -
drivers/xen/blkfront/blkfront.c). The later caused incorrect device
flags (RO/removable etc).
