RFR: 8325202: gc/g1/TestMarkStackOverflow.java intermittently crash: G1CMMarkStack::ChunkAllocator::allocate_new_chunk

[Ivan Walulya]

Please review this bug fix to guarantee that expanding the G1CMMarkStack considers the expected capacity for the thread triggering the expansion instead of expanding based on current capacity. 

Testing: - Tier 1 -3 
               - 2M test iterations (bug is reproducible ~1/100k test iterations)
