From: Raghava Aditya Renukunta <raghavaaditya.renukunta@pmcs.com>

while driver removal is in progress or PCI shutdown is invoked, driver
kills AIF aacraid thread, but IOCTL requests from the management tools
re-start AIF thread leading to IOP_RESET.

Fixed by setting adapter_shutdown flag when PCI shutdown is invoked.

Changes in V2:
Set adapter_shutdown flag before shutdown command is sent to \
controller
