scsi: pm8001: Fix tag values handling
The function pm8001_tag_alloc() determines free tags using the function
find_first_zero_bit() which can return 0 when the first bit of the bitmap
being inspected is 0. As such, tag 0 is a valid tag value that should not
be dismissed as invalid. Fix the functions pm8001_work_fn(),
mpi_sata_completion(), pm8001_mpi_task_abort_resp() and
pm8001_open_reject_retry() to not dismiss 0 tags as invalid.
The value 0xffffffff is used for invalid tags for unused ccb information
structures. Add the macro definition PM8001_INVALID_TAG to define this
value.
