[None][fix] Remove leftover onboardBlocks param in kvCacheManagerTest

[eopXD]

Description

Commit ec34644 ("[None][chore] Remove onboard block switch for KV cache manager (#12449)") removed the onboardBlocks parameter from the KVCacheManager constructor but missed the StoreBlocksForReuseWithPinDoesNotCreateGhostFreeBlocks test case in kvCacheManagerTest.cpp, causing a compilation error.

This PR removes the leftover onboardBlocks variable and its usage from the constructor call.

Test Coverage

• The fix is removing a stale argument from an existing test. No new tests needed.
• The affected test (StoreBlocksForReuseWithPinDoesNotCreateGhostFreeBlocks) will now compile and run correctly.
