As evidenced by how other filesystems handle it, a return value of 0 from fs_devread() means failure; nonzero means success. The opposite assumption was being made in zfs.c for the use of zfs_devread() so fix the confusion by making zfs_devread() return 0 on success. It probably doesn't make sense to change the handling of zfs_devread() in zfs.c instead, because as it is it matches the semantics of the other functions there.
