From: Sawan Chandak <sawan.chan...@cavium.com>
Driver will perform following
- Set PFLG_DRIVER_REMOVING flag and do not disable PCIe
error reporting during adapter shutdown.
- If PCIe device count is already zero, return correct
error type from PCI error interface.
- When device is offline, return correct error type from
PCIe error path.
- If there is board disable thread active during shutdown
and PCIe device count is zero then cancel scheduling board
disable thread during shutdown and return.
