Change num_inbound_wins from u8 to int to correctly handle
potential negative error codes returned by brcm_pcie_get_inbound_wins().
The u8 type was inappropriate for capturing the function's return value,
which can include error codes.

I squashed with the current code on the controller/brcmstb branch, see:

  - https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/commit/?h=controller/brcmstb&id=ae6476c6de187bea90c729e3e0188143300fa671

And credited you via the Co-developed-by tag such that you get credit for
fixing this issue.  Thank you, by the way.

There is no Fixes: tag as this code is not yet merged into the mainline.

For the record, I would prefer if we went with Florian's first
recommendation per the following message:

  - https://lore.kernel.org/linux-pci/159c5fcf-709d-42ba-8d45-a70b109fe261@broadcom.com

To clearly separate errors returned from the value being updated.

Albeit, this is fine too, especially as Jim expressed no opinion either
way regarding his preference.
