BUG/MINOR: fd/threads: properly dereference fdcache as volatile

In fd_rm_from_fd_list(), we have loops waiting for another change to
complete, in case we don't have support for a double CAS. But these
ones fail to place a compiler barrier or to dereference the fdcache
as a volatile, resulting in an endless loop on the first collision,
which is visible when run on MIPS32.

No backport needed.
