[PATCH xserver 2/2] ranrd: Do not update ConnectionInfo if NULL

[Olivier Fourdan]

RRScreenSizeNotify() will update the connection information block, but
if this occurs during initialization before ConnectionInfo is even
initialized, this will lead to a crash.

Simply check for ConnectionInfo prior to update it to avoid the crash.
