net: wwan: t7xx: Fix Runtime PM initialization
[ Upstream commit e3d6d152a1cbdee25f2e3962009a2751b54e2297 ]
For PCI devices the Runtime PM refcount is incremented twice:
1. During device enumeration with a call to pm_runtime_forbid.
2. Just before a driver probe logic is called.
Because of that in order to enable Runtime PM on a given device
we have to call both pm_runtime_allow and pm_runtime_put_noidle,
once it's ready to be runtime suspended.
The former was missing causing the pm refcount to never reach 0.
Fixes: d10b3a695ba0 ("net: wwan: t7xx: Runtime PM")
