Uros Bizjak 89422df954 ALSA: usb-audio: Use atomic_try_cmpxchg in ep_state_update 
Use atomic_try_cmpxchg instead of atomic_cmpxchg (*ptr, old, new) == old in
ep_state_update. x86 CMPXCHG instruction returns success in ZF flag,
so this change saves a compare after cmpxchg (and related move instruction
in front of cmpxchg).

No functional change intended.
