kernel/module: improve documentation for try_module_get()

    kernel/module: improve documentation for try_module_get()

    removed" is potentially confusing and may contradict the rest of the
    documentation. If one tries to get a module that has already been
    removed using a stale pointer, the kernel will crash.
