[PATCH net-next 7/7] net: ipa: kill ipa_power_modem_queue_wake()

[Alex Elder]

All ipa_power_modem_queue_wake() does is call netif_wake_queue()
on the modem netdev.  There is no need to wrap that call in a
trivial function (and certainly not one defined in "ipa_power.c").

So get rid of ipa_power_modem_queue_wake(), and replace its one
caller with a direct call to netif_wake_queue().  Determine the
netdev pointer to use from the private TX endpoint's netdev pointer.
