Using IWL_MVM_STATION_COUNT and IWL_INVALID_STATION together
isn't a good idea as they have different values. Always use
IWL_MVM_STATION_COUNT for an invalid station in MVM and move
the definition of the IWL_INVALID_STATION constant into the
DVM driver to avoid making such mistakes again. The one use
in the transport code can be hard-coded to -1 instead as the
station ID is passed as an integer there.

iwlwifi: sleep for at least 10 seconds
Many platforms have issues processing a wakeup signal
while they're still suspending, and will ignore it.
Since our device thinks it woke the platform, and the
platform ignored the signal, it will sleep without
WoWLAN being enabled as the device disables WoWLAN
when having woken the platform.
Resolve this by making the device wait for 10 seconds
after getting the suspend signal before waking up the
platform.
