phy: qcom-qmp-combo: fix init-count imbalance
The init counter is not decremented on initialisation errors, which
prevents retrying initialisation and can lead to the runtime suspend
callback attempting to disable resources that have never been enabled.
Add the missing decrement on initialisation errors so that the counter
reflects the state of the device.
Fixes: e78f3d15e115 ("phy: qcom-qmp: new qmp phy driver for qcom-chipsets")
