MdeModulePkg/Bus/Ata/AtaAtapiPassThru: Fix SIGN_EXTENSION Coverity issue
Line number 1348 does contain a typecast with UINT32, but it is after
all the operations (16-bit left shift followed by OR'ing) are over.
To avoid any SIGN_EXTENSION, typecast the intermediate result after
16-bit left shift operation immediately with UINT32.

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.
