HwDisableInterruptsCallback Routine

A HwDisableInterruptsCallback routine should do the following:

1 Reenable interrupts from the HBA.

2 Return control.

Note that this routine must execute as quickly as possible to avoid tying up I/O operations for other devices in the machine. Consequently, a HwEnableInterruptsCallback must do no more than reenable interrupts on the HBA before it returns control.
