MdeModulePkg/Bus/Ata/AtaAtapiPassThru: Fix UNUSED_VALUE Coverity issue

The return value stored in Status after call to SetDriveParameters
is not made of any use thereafter and hence it remains as UNUSED.

Based on Hao's findings (https://edk2.groups.io/g/devel/message/106844),
the successful execution of SetDriveParameters() is not mandatory for
initializing IDE mode of a hard disk device. Hence remove the 'Status'
assignment of the return value from SetDriveParameters() and instead add
error checks & DEBUG_WARN level messages within SetDriveParameters()
function after sending INIT_DRIVE_PARAM & SET_MULTIPLE_MODE ATA commands.
