[PATCH 07/13] x86/paravirt: Simplify ____PVOP_CALL()
Remove the inline asm duplication in ____PVOP_CALL().
Also add 'IS_ENABLED(CONFIG_X86_32)' to the return variable logic,
making the code clearer and rendering the comment unnecessary.

[PATCH v3 04/12] Revert "x86/paravirt: Work around GCC inlining bugs when compiling paravirt ops"
This reverts commit 494b5168f2de009eb80f198f668da374295098dd.
The in-kernel workarounds will be replaced with GCC's new
"asm inline" syntax.
