nvme-pci: use unsigned for io queue depth
The NVMe PCIe declares module parameter io_queue_depth as int. Change this to u16 as queue depth can never be negative. Now to reflect this update module parameter getter function from param_get_int() -> param_get_uint() and respective setter function with type of n changed from int to u16 with param_set_int() to param_set_ushort(). Finally update struct nvme_dev q_depth member to u16 and use u16 in min_t() when calculating dev->q_depth in the nvme_pci_enable() (since q_depth is now u16) and use unsigned int instead of int when calculating dev->tagset.queue_depth as target variable tagset->queue_depth is of type unsigned int in nvme_dev_add().
