Chandrakanth patil ad347c4638 scsi: megaraid_sas: Increase register read retry rount from 3 to 30 for selected registers 
commit 8e3ed9e786511ad800c33605ed904b9de49323cf upstream.

In BMC environments with concurrent access to multiple registers, certain
registers occasionally yield a value of 0 even after 3 retries due to
hardware errata. As a fix, we have extended the retry count from 3 to 30.

The same errata applies to the mpt3sas driver, and a similar patch has
been accepted. Please find more details in the mpt3sas patch reference
link.
