x86/tdx: Wrap exit reason with hcall_func()
TDX reuses VMEXIT "reasons" in its guest->host hypercall ABI. This is
confusing because there might not be a VMEXIT involved at *all*.
These instances are supposed to document situation and reduce confusion
by wrapping VMEXIT reasons with hcall_func().
The decompression code does not follow this convention.
Unify the TDX decompression code with the other TDX use of VMEXIT reasons.
No functional changes.
