[PATCH 1/2] scsi: ufs: Fix interrupt error message for shared interrupts

[Adrian Hunter <adrian.hunter@intel.com>]

The interrupt might be shared, in which case it is not an error for the
interrupt handler to be called when the interrupt status is zero, so
remove the message print and register dump.
