Subject: [PATCH v19 008/130] x86/tdx: Warning with 32bit build shift-count-overflow

From: Isaku Yamahata <isaku.yamahata@...el.com>

This patch fixes the following warnings.

   In file included from arch/x86/kernel/asm-offsets.c:22:
   arch/x86/include/asm/tdx.h:92:87: warning: shift count >= width of type [-Wshift-count-overflow]
   arch/x86/include/asm/tdx.h:20:21: note: expanded from macro 'TDX_ERROR'
   #define TDX_ERROR                       _BITUL(63)

                                           ^~~~~~~~~~

Also consistently use ULL for TDX_SEAMCALL_VMFAILINVALID.

Fixes: 527a534c7326 ("x86/tdx: Provide common base for SEAMCALL and TDCALL C wrappers")
