Kernel: Pass NVMeController reference to NVMequeue

Browse source 
This is in preparation for adding MSI(x) support to the NVMe device.
NVMeInterruptQueue needs access to the PCI device to deal with MSI(x)
interrupts. It is ok to pass the NVMeController as a reference to the
NVMeQueue as NVMeController is the one that owns the NVMeQueue.

This is very similar to how AHCIController passes its reference to its
interrupt handler.
