cmssw: [GPU] Multiple RelVals failing with memory allocation error

Hello,

There are multiple RelVals failing with the following exception in GPU IBs:

----- Begin Fatal Exception 05-Feb-2024 04:19:50 CET-----------------------
An exception of category 'StdException' occurred while

cudaCheck(error = cudaMalloc(&search_key.d_ptr, search_key.bytes));
cudaErrorMemoryAllocation: out of memory
----- End Fatal Exception -------------------------------------------------

It seems caused by modifications in https://github.com/cms-sw/cmssw/pull/43804.

FYI, @iarspider

Thanks, Andrea
