PCI: mobiveil: Fix the valid check for inbound and outbound windows
[ Upstream commit ccd34dac2ed596b1f26079912bdf638e002a3979 ]
In program_ib/ob_windows() check the window index from the function
parameter instead of the total number of initialized windows to
determine if the specified window is valid.
Fixes: 9af6bcb11e12 ("PCI: mobiveil: Add Mobiveil PCIe Host Bridge IP driver")
