x86/tdx: Skip saving output regs when SEAMCALL fails with VMFailInvalid
If SEAMCALL fails with VMFailInvalid, the SEAM software (e.g., the TDX
module) won't have chance to set any output register. Skip saving the
output registers to the structure in this case.
Also, as '.Lno_output_struct' is the very last symbol before RET, rename
it to '.Lout' to make it short.
Opportunistically make the asm directives unindented.
