    net/samba425: avoid SIGFPE in streams_xattr_get_ea_value_fsp
    
    As reported in https://bugzilla.samba.org/show_bug.cgi?id=16278,
    upstream commit 5fa43440ebd3 ("vfs: Implement larger streams in multiple
    xattrs"), results in many signal 8 (SIGFPE) crashes in smbd child
    processes on FreeBSD, if the streams_xattr vfs module is loaded.
    
    This is because streams_xattr_get_ea_value_fsp() can divide by zero, if
    the "max xattrs per stream" is left at its default value.
    
    Apply the upstream fix to avoid the crashes.
