Interrupt context storage is statically allocated at the time interrupts are allocated. Following allocation, the interrupt context is managed by directly accessing the elements of the array using the vector as index. It is possible to allocate additional MSI-X vectors after MSI-X has been enabled. Dynamic storage of interrupt context is needed to support adding new MSI-X vectors after initial allocation. Replace direct access of array elements with pointers to the array elements. Doing so reduces impact of moving to a new data structure. Move interactions with the array to helpers to mostly contain changes needed to transition to a dynamic data structure. No functional change intended.
