qcacld-2.0: Register Callback for fullPower before posting message

Browse source 
prima to qcacld-2.0 propagation

In pmcRequestFullPower, driver is posting message to enter
in full power with wpa_supplicant thread.
 After posting message to enter in full power
context has been switched to MC thread.
MC thread starts processing IMPS RESPONSE, even before Supplicant
thread can add callback entry to requestFullPowerList,
so in effect the IMPS response handler does not invoke any callbacks,
 and command sitting in roam pending list does not get processed.
Fix this by posting callback before posting message to enter in
full power. If enter full power get fails remove the entry.
