[PATCH] wifi: wlcore: Fix runtime PM leak in wlcore_remove()

[Wentao Liang]

pm_runtime_get_sync() keeps the runtime PM usage counter elevated even
when it returns an error, so the reference taken at the beginning of
wlcore_remove() has to be dropped on every exit path. When the device
was not initialized the function returned early without doing so,
leaking the reference.

Release it with pm_runtime_put_noidle() as done on the other early error
paths of this driver.
