Initialize mnt_stat.f_iosize before autostarting UFS1 extattrs.
It is normally initialized by ffs_statfs() after ffs_mount finished.

The extattr autostart code calls the ufs_lookup(), that uses value above
to iterate over the directory blocks, see bmask initialization in the
ufs_lookup() and ufsdirhash. Having the filesystem with root directory
spanning more then one block would result in reading a random kernel
memory.
