53C895A datasheet says:
"This bit (DFE) is a pure status bit and will not cause an interrupt"
This bit is already auto-generated in lsi_read_reg when reading the DSTAT
register.
This fixes IBM RS/6000 7020 firmware, which is:
- resetting the adapter
- enabling all interrupt sources (including DIP, ie interrupts from DSTAT)
- waiting for ISTAT0 to become 0 (including DIP=0, ie no interrupt coming from
DSTAT)
