        src/lib/libc/atomic: membar_ops.3

Log Message:
Reword advice about when not to use membar_exit.

With help from skrll and pgoyette.

While here, change the example so it doesn't violate the advice just
given.  Still not a great example -- abusing UINT_MAX for a reference
count is kinda sketchy, but it'll serve for now.
