DRI2: Fix glitches in DRI2SwapComplete() and DRI2WakeupClient()

Browse Source 
DRI2SwapComplete(): Increment pPriv->swap_count++; before calling
into callback for INTEL_swap_events extension, so the swap event
contains the current SBC after swap completion instead of the
previous one.

DRI2WakeupClient: Check for pPriv->target_sbc <= pPriv->swap_count,
had wrong comparison pPriv->target_sbc >= pPriv->swap_count for
unblocking of clients of DRI2WaitSBC().
