description:
G/c unused rwlock owner macros copy-pasted from the kernel.

They were brought along with the rwlock flags but never used and never
even adapted to the new home (the struct member name is different
here).  I looked at adapting and using them, but they don't really
help readability that much and there are cases where we need to deal
with "fused" owner values anyway and so can't use them.
