Fix A_CheckProximity setting pointer to dead things when it shouldn't.

Browse source 
When using A_CheckProximity with CPXF_SETTARGET, the target pointer could
be set to a dead monster even without the CPXF_COUNTDEAD and CPXF_DEADONLY
flags. This is becuase the check for death would occur after setting the
pointer.

Fix simply moves death check to occur before setting pointers.
