protocol/client: Do not fallback to anon-fd if fd is not open
If an open comes on a file when a brick is down and after the brick comes up,
a fop comes on the fd, client xlator would still wind the fop on anon-fd
leading to wrong behavior of the fops in some cases.
Example:
If lk fop is issued on the fd just after the brick is up in the scenario above,
lk fop will be sent on anon-fd instead of failing it on that client xlator.
This lock will never be freed upon close of the fd as flush on anon-fd is
invalid and is not wound below server xlator.
As a fix, failing the fop unless the fd has FALLBACK_TO_ANON_FD flag.
