Getting 'multipathd: sdx: update path write_protect to '0' (uevent)' messages during SCSI device rescan

Issue

• RHEL/RHV servers are logging following errors during device rescan.

• Couple of LUNs on these servers are added to EMC SRDF and these LUNs are kept in read-only state. There are no changes done with LUN Read/Write state from SRDF configuration, but multipathd still reports a change in RO/RW state:
