qcacmn: Cancel sleep_timer completely in pcie bus suspend

There is possibility that sleep_timer is in running state,
so even in hif_pci_cancel_deferred_target_sleep timer has
been stopped, it runs later.

Use fake_sleep in hif_sleep_entry to check if timer has been
stopped, if yes, without action in hif_sleep_entry.
