RFR(XXS): 8214125: [test] Fix comparison between pointer and integer in test_ptrQueueBufferAllocator.cpp

[Thomas Stüfe]

Looks good and trivial.

I remember running into this before, see 8171225. What I do not understand
is, should NULL not be (void*)0 according to Posix:
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/stddef.h.html ? So
this should be a pointer-pointer comparison.

Maybe we just miss include <stddef.h> somehow on AIX?
