Bjorn Andersson aaaa7a6006 slimbus: qcom-ngd-ctrl: Avoid sending power requests without QMI 
[ Upstream commit 39014ce6d6028614a46395923a2c92d058b6fa87 ]

Attempting to send a power request during PM operations, when the QMI
handle isn't initialized results in a NULL pointer dereference. So check
if the QMI handle has been initialized before attempting to post the
power requests.

Fixes: 917809e228 ("slimbus: ngd: Add qcom SLIMBus NGD driver")
