glxext.c: fix another memory leak

==10226== 3,337 bytes in 1 blocks are definitely lost in loss record 295 of 307
==10226==    at 0x483577F: malloc (vg_replace_malloc.c:299)
==10226==    by 0x6281DB9: strdup (strdup.c:42)
==10226==    by 0x2ABA9E: __glXClientInfo (glxcmds.c:2170)
==10226==    by 0x17CA3E: __glXDispatch (NXglxext.c:128)
==10226==    by 0x16EE77: Dispatch (NXdispatch.c:476)
==10226==    by 0x14DCE0: main (main.c:353)

There's no point in trying to free cl->* after memset(0).

This one is a bug that is found identically in xorg upstream and has
only been fixed during rework of the whole client resource freeing
stuff. So we fix it in glxext.c.
