scsi: megaraid_sas: Update max supported LD IDs to 240



The firmware only supports Logical Disk IDs up to 240 and LD ID 255 (0xFF)
is reserved for deleted LDs. However, in some cases, firmware was assigning
LD ID 254 (0xFE) to deleted LDs and this was causing the driver to mark the
wrong disk as deleted. This in turn caused the wrong disk device to be
taken offline by the SCSI midlayer.

To address this issue, limit the LD ID range from 255 to 240. This ensures
the deleted LD ID is properly identified and removed by the driver without
accidently deleting any valid LDs.
