Peter Zijlstra 427b18207a locking/mutex: Improve inlining
Instead of inlining __mutex_lock_common() 5 times, once for each
{state,ww} variant. Reduce this to two, ww and !ww.

Then add __always_inline to mutex_optimistic_spin(), so that that will
get inlined all 4 remaining times, for all {waiter,ww} variants.

   text    data     bss     dec     hex filename

   6301       0       0    6301    189d defconfig-build/kernel/locking/mutex.o
   4053       0       0    4053     fd5 defconfig-build/kernel/locking/mutex.o
   4257       0       0    4257    10a1 defconfig-build/kernel/locking/mutex.o

This reduces total text size and better separates the ww and !ww mutex
code generation.
