Pull target fixes from Nicholas Bellinger:
 "This includes a bugfix from MDR to address a NULL pointer OOPs with
  FCoE aborts, along with a WRITE_SAME emulation bugfix for NOLB=0
  cases, and persistent reservation return cleanups from Roland.

  All three patches are CC'ed to stable."

  target: Fix range calculation in WRITE SAME emulation when num blocks == 0
  target: Clean up returning errors in PR handling code
  tcm_fc: Fix crash seen with aborts and large reads
