PCI: Try BAR resize even when no window was released

Browse source

Usually, resizing BARs requires releasing bridge windows in order to
resize it to fit a larger BAR into the window. This is not always the
case, however, FW could have made the window large enough to accommodate
larger BAR as is, or the user might prefer to shrink a BAR to make more
space for another Resizable BAR.

Thus, replace the check that requires that at least one bridge window
was released with a check that simply ensures bridge is not NULL.
