Daniil Tatianin e5f2e4c696 pciinit: don't misalign large BARs 
Previously we would unconditionally lower the alignment for large BARs
in case their alignment was greater than "pci_mem64_top >> 11", this
would make it impossible to use these devices by the kernel:
    [   13.821108] pci 0000:9c:00.0: can't claim BAR 1 [mem 0x66000000000-0x67fffffffff 64bit pref]: no compatible bridge window
    [   13.823492] pci 0000:9d:00.0: can't claim BAR 1 [mem 0x64000000000-0x65fffffffff 64bit pref]: no compatible bridge window
    [   13.824218] pci 0000:9e:00.0: can't claim BAR 1 [mem 0x62000000000-0x63fffffffff 64bit pref]: no compatible bridge window
    [   13.828322] pci 0000:8a:00.0: can't claim BAR 1 [mem 0x6e000000000-0x6ffffffffff 64bit pref]: no compatible bridge window
    [   13.830691] pci 0000:8b:00.0: can't claim BAR 1 [mem 0x6c000000000-0x6dfffffffff 64bit pref]: no compatible bridge window
    [   13.832218] pci 0000:8c:00.0: can't claim BAR 1 [mem 0x6a000000000-0x6bfffffffff 64bit pref]: no compatible bridge window

Fix it by only overwriting the alignment in case it's actually greater
than the desired by the BAR window.

Fixes: 96a8d130a8 ("be less conservative with the 64bit pci io window")
