[PATCH v6 5/6] x86/vdso: Use CFI macros in __vdso_sgx_enter_enclave()

[Jens Remus <jremus@linux.ibm.com>]

From: Josh Poimboeuf <jpoimboe@kernel.org>

Use the CFI macros instead of the raw .cfi_* directives to be consistent
with the rest of the VDSO asm.  It's also easier on the eyes.

No functional changes.
