    dri2: Fix detection of wrong prime_id in GetScreenPrime.
    
    Checking the iterating variable ("slave") against null can not detect if the
    xorg_list_for_each_entry finished without break being invoked - slave variable
    will be always non-null. This caused segfault whenever someone tried to use
    DRI_PRIME with incorrect id while having at least one render offloading slave
    configured.
    
    Restructurize the GetScreenPrime to work as expected.
