PCI: cleanup Function Level Reset
This patch enhances the FLR functions:
1) remove disable_irq() so the shared IRQ won't be disabled.
2) replace the 1s wait with 100, 200 and 400ms wait intervals
for the Pending Transaction.
3) replace mdelay() with msleep().
4) add might_sleep().
5) lock the device to prevent PM suspend from accessing the CSRs
during the reset.
6) coding style fixes.
