MdeModulePkg/UfsPassThruDxe: Fix v2 protocol backward compatibility
Commit b58ce4c226 broke backward compatibility with v2 platform
protocols by incorrectly skipping HCE re-enable for v2 implementations.
When used with a UfsPlatform.efi binary that was compiled against
an older stable tag, (where EDKII_UFS_HC_PLATFORM_PROTOCOL_VERSION
is defined as 2), the code attempted to read the v3-only
SkipHceReenable/SkipLinkStartup fields beyond the v2 struct boundary,
reading garbage memory and potentially skipping initialization.
Add explicit version check to ensure v2 protocols follow normal
initialization path, preventing out-of-bounds struct access.
TEST=build/boot google/yaviks with UFS storage
