[PATCH:libXfont 3/3] fs_send_open_font needs to allow namelen of 0 when FontReopen is set

[Alan Coopersmith]

When _fs_load_glyphs calls fs_send_open_font with FontReopen set, it
passes a NULL name and namelen of 0, since fs_send_open_font is going
to reuse the previous name.

This overly restrictive check was added in XFree86 4.3.99.12:
