[PATCH v2 1/2] MdeModulePkg/Bus/Ata/AtaAtapiPassThru: Fix SIGN_EXTENSION Coverity issue

[Ranbir Singh <rsingh@ventanamicro.com>]

From: Ranbir Singh <Ranbir.Singh3@Dell.com>

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.
