Linux MegaRAID SAS fixes (#15566)

* Linux MegaRAID SAS fixes
 - Updated disk error threshold from 1 to 0.1 because we need to know when
   it reaches 1, not when it exceeds 1.  It would ideally be set to 0, but
   it needs to evaluate to true in order for the threshold to be set.
 - Fixed the OID for the virtual disk failure check, which also removes the
   duplicate check on the predictive failure OID

* Updated the LSI test output

* Another update to the SNMP results

* Update all thresholds to 0

The warning and error thresholds work correctly when set to 0, so I have updated these values

* Change back to the original sensor OID, with the correct MIB OID and description

* Further re-classification of degraded LSI disk check
