randr: set error numbers of resource types in RRExtenstionInit() (V2)

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367 Currently the ddx calls xf86RandR12Init() (-> RRScreenInit() -> RRInit() -> RRModeInit() -> RRCrtcInit() -> RROutputInit()) before RRExtensionInit() is called. This causes RRErrorBase being 0 while setting resource type error values (resource types: RROutput, RRMode and RRCrtc). The fix moves the setting of error values to own functions which are called in RRExtensionInit() to get the right RRErrorBase.
