[SCSI] scsi_dh_rdac: Retry for Quiescence in Progress in rdac device handler
During device discovery read capacity fails with 0x068b02 and sets the device size to 0. As a reason any I/O submitted to this path gets killed at sd_prep_fn with BLKPREP_KILL. This patch is to retry for 0x068b02 Signed-off-by: Vijay Chauhan <vijay.chauhan@lsi.com> Acked-by: Chandra Seetharaman <sekharan@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
