[PATCH V3 0/2] nvme: fix iod size calculation in nvme_probe()

[Chaitanya Kulkarni]

Hi,

This is a small patch series which fixes the IO size calulation in the
nvme_probe.

The first patch replaces the ctrl->page_size with a macro. The second
patch calculates the maximum value based on NVMe PRP and SGL size.

I've tested this patch with different block sizes 4k-128k on NVMe QEMU
and NVMe PCIe (non-SGL) controller.

Regards,
Chaitanya

* Changes from V2:-
-------------------

1. Modify commit log for patch 1.
2. Repalace ilog2(NVME_CTRL_PAGE_SIZE) ->  NVME_CTRL_PAGE_SHIFT.

* Changes from V1:-
-------------------

1. Remove the ctrl->page_size and use macro instead.
2. Get rid of the conditional operater and use max_t() for SGL vs PRP
   size calulation.

  nvme-pci: use max of PRP or SGL for iod size
