[SCSI] mptfusion: Added check for SILI bit in READ_16 CDB for DATA UNDERRUN ERRATA
When READ_16 command is issued, the setting of SILI Bit in CDB is confirmed and if SILI bit is off, the processing of relavent Errata is executed. Added code for checking SILI bit for READ_16 as described in "SSC-4". Signed-off-by: Nagalakshmi Nandigama <nagalakshmi.nandigama@lsi.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
