[NTOSKRNL:CC] CcSetDirtyPinnedData :: use reconstructed OBCB Structure

Browse Source 
Their no PBCB anymore, since we reconstructed it by looking at _OBCB  which is reconstructed from CcAllocateObcb, 
we know that bcb array is array of PCC_BCB structure, thus modified CcSetDirtyPinnedData to use OBCB instead
