Bug description:
[Impact]

This update has been initiated to include a few critical bug fixes
from upstream into the 22.04.04 point kernel via SRU. 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

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
