Fixed an incorrect struct initialization

[ldh4]

Building Kokkos for a HIP build with -DKokkos_ENABLE_HIP_RELOCATABLE_DEVICE_CODE=ON produced an error:

[  4%] Building CXX object core/src/CMakeFiles/kokkoscore.dir/desul/src/Lock_Array_HIP.cpp.o

It turned out that there was a HIPLockArrays struct variable that was being initialized incorrectly.

Bug was introduced in #4371

[dalg24]

This needs to be cherry picked in the patch release

NVHPC failure is the issue reported in #5025
