Fix incorrect reference in Queue

[Username404-59]

Fixes an issue I had when building amdvlk with clang 19:

/var/tmp/portage/media-libs/amdvlk-2024.3.3/work/pal/shared/devdriver/shared/legacy/inc/util/queue.h:371:25: error: no member named 'allocCb' in 'Queue<T, BlockSize, MinIndexCacheSize>'; did you mean 'm_allocCb'?
  371 |             : Queue(rhs.allocCb)
      |                         ^~~~~~~
      |                         m_allocCb
/var/tmp/portage/media-libs/amdvlk-2024.3.3/work/pal/shared/devdriver/shared/legacy/inc/util/queue.h:367:17: note: 'm_allocCb' declared here
  367 |         AllocCb m_allocCb;

Thanks for the fix!
This has been merged internally and should appear in one of the next releases (probably not the next one due to release cycles and changes taking time to propagate).
