MdeModulePkg/Bus/Ata/AtaBusDxe: Fix SIGN_EXTENSION Coverity issue
Line number 365 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.
