Jinliang Zheng f84a15b90d locking/rwsem: Use OWNER_NONSPINNABLE directly instead of OWNER_SPINNABLE 
After commit 7d43f1ce9d ("locking/rwsem: Enable time-based spinning on
reader-owned rwsem"), OWNER_SPINNABLE contains all possible values except
OWNER_NONSPINNABLE, namely OWNER_NULL | OWNER_WRITER | OWNER_READER.

Therefore, it is better to use OWNER_NONSPINNABLE directly to determine
whether to exit optimistic spin.

And, remove useless OWNER_SPINNABLE to simplify the code.
