shmem: factor shmem_falloc_wait() out of shmem_fault()
That Trinity livelock shmem_falloc avoidance block is unlikely, and a
distraction from the proper business of shmem_fault(): separate it out.
(This used to help compilers save stack on the fault path too, but both
gcc and clang nowadays seem to make better choices anyway.)
