[PATCH] randr: set error numbers of resource types in RRExtenstionInit() #30367

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367

Currently the ddx calls RROutputInit() before RRExtensionInit() is
called. This causes RRErrorBase being 0 while setting resource type
error (resource types RROutput, RRMode and RRCrtc).
The fix moves the setting of error numbers to RRExtensionInit() to get
the right RRErrorBase.
