[PATCH 1/2] PCI: leave MEM and IO decoding disabled during 64-bit BAR sizing, too

After 253d2e5498, we disable MEM and IO decoding for most devices while we size 32-bit BARs. However, we restore the original COMMAND register before we size the upper 32 bits of 64-bit BARs, so we can still cause a conflict. This patch waits to restore the original COMMAND register until we're c
