qcacld-3.0: Apps cannot power collapse while wifi is on

Under error conditions while suspending FW, the target-suspended flag
was not being cleared properly. This caused a situation where FW was
thought to be suspended, but was not. This prevented Apps from
suspending. Properly unsetting this flag under error conditions was
added in this change.
