Ajish Koshy 80cac47b08 scsi: pm80xx: Handle non-fatal errors
Firmware expects host driver to clear scratchpad rsvd 0 register after
non-fatal error is found.

This is done when firmware raises fatal error interrupt and indicates
non-fatal error. At this point firmware updates scratchpad rsvd 0 register
with non-fatal error value. Here host has to clear the register after
reading it during non-fatal errors.

Rename:

 - MSGU_HOST_SCRATCH_PAD_6 to MSGU_SCRATCH_PAD_RSVD_0

 - MSGU_HOST_SCRATCH_PAD_7 to MSGU_SCRATCH_PAD_RSVD_1
