[PATCH RESEND] x86/local: Remove trailing semicolon from _ASM_XADD in local_add_return()

[Uros Bizjak <ubizjak@gmail.com>]

Remove the trailing semicolon from the inline assembly statement in
local_add_return().

The _ASM_XADD macro already expands to a complete instruction, making
the extra semicolon unnecessary. More importantly, the stray semicolon
causes GCC to treat the inline asm as containing multiple instructions,
which can skew its internal instruction count estimation and affect
optimization heuristics.

No functional change intended.
