scsi: ufs: reduce UFS dump prints for error case

When UFS controller reports an error a dump is printed to
aid debugging. In certain cases the print outs is too excesive
and not all the information is really needed. In addition, printing
is done from interrupt context so long prints might cause the target
to crash.
This change reduces the amount of data printed out and moves part of
the printing to the worker thread context.
