    xfs: prevent reading uninitialized stack memory
    
    The XFS_IOC_FSGETXATTR ioctl allows unprivileged users to read 12
    bytes of uninitialized stack memory, because the fsxattr struct
    declared on the stack in xfs_ioc_fsgetxattr() does not alter (or zero)
    the 12-byte fsx_pad member before copying it back to the user.  This
    patch takes care of it.
