[PATCH] dri2: Register the DRI2DrawableType after server regeneration

> The Resource database is reset upon regeneration and so the dri2 module

> xf86-video-intel started using the Resource database to track

How to reproduce the bug fixed by this patch:

# X -retro :0
# DISPLAY=:0 glxinfo
# DISPLAY=:0 glxinfo

After the second glxinfo, X will crash. Notice that you can't have
other X clients, so you can trigger new server generations.
