v2--v3:
  Based on Bean's comments:
  1)Use kzalloc instead of kmalloc in ufshcd_set_active_icc_lvl - patch 2/4
  2)Delete  UFS_RPMB_UNIT definition - patch 2/4
  3)Delete len description - patch 3/4

v1--v2:
  Fix argument warning in ufshpb.c

Read any descriptor with a maximum size of QUERY_DESC_MAX_SIZE.
According to the spec the device rerurns the actual size.
Thus can improve code readability and save CPU cycles.
While at it, cleanup few leftovers around the descriptor size parameter.
