qcacld-3.0: Acquire wakelock during roaming if key installation is pending

Ver código fonte 
Currently, wakelock is only taken during initial connection if
pairwise key installation is pending and not during roaming. This
may lead to EAPOL delay/timeout during roaming as runtime pm and
suspend is allowed during roaming. To fix this issue, acquire
wakelock if key installation is pending during roaming.

This change also refactors the code and release the wakelock in
wma_remove_peer if EAPOL fails during initial connection or roaming.
