x86/alternatives: Add missing '\n' at end of ALTERNATIVE inline asm

commit b9e705ef7cfaf22db0daab91ad3cd33b0fa32eb9 upstream.

Where an ALTERNATIVE is used in the middle of an inline asm block, this
would otherwise lead to the following instruction being appended directly
to the trailing ".popsection", and a failed compile.

Fixes: 9cebed423c84 ("x86, alternative: Use .pushsection/.popsection")
