x86/tdx: Do not corrupt frame-pointer in __tdx_hypercall()
If compiled with CONFIG_FRAME_POINTER=y, objtool is not happy that
__tdx_hypercall() messes up RBP:
objtool: __tdx_hypercall+0x7f: return with modified stack frame
Rework the function to store TDX_HCALL_ flags on stack instead of RBP.
[ dhansen: minor changelog tweaks ]
Fixes: c30c4b2555ba ("x86/tdx: Refactor __tdx_hypercall() to allow pass down more arguments")
