SRU Justification:

[Impact]

This update has been initiated to include a few critical bug fixes from upstream into the upcoming 22.04.04 point kernel. Below are the upstream commit IDs:

[Fix]
0938f9fa4208 scsi: megaraid_sas: Driver version update to 07.727.03.00-rc1
2d83fb023c90 scsi: megaraid_sas: Log message when controller reset is requested but not issued
8e3ed9e78651 scsi: megaraid_sas: Increase register read retry count from 3 to 30 for selected registers
0b0747d507bf scsi: megaraid_sas: Fix deadlock on firmware crashdump
2309df27111a scsi: megaraid_sas: Fix crash after a double completion
0808ed6ebbc2 scsi: megaraid_sas: Fix fw_crash_buffer_show()

The change log for the above commit IDs is small and doesn't require rigorous validation. So please include these patches.

[Test Plan]

1. Driver load and unload
2. Create and delete different virtual drives (R0, R1, R5 etc.,)
3. create JBOD
4. Run IOs with different profiles (io_depth, io_size etc.,) on VD and JBOD
5. controller reset while running IOs

[ Where problems could occur ]
It has a critical patch which fixes the issue related to various register reads. So IO runs and various internal commands where problems could occur
