When Test Unit Ready command succeeds, retrieve Sense Keys via Request Sense; When Test Unit Ready command encounters any error caused by host adapter or target, return error without retrieving Sense Keys.

Parameters

ScsiDiskDevice	The pointer of SCSI_DISK_DEV
NeedRetry	The pointer of flag indicates try again
SenseDataArray	The pointer of an array of sense data
NumberOfSenseKeys	The pointer of the number of sense data array

Return values

EFI_DEVICE_ERROR	Indicates that error occurs
EFI_SUCCESS	Successfully to test unit
