qcacld-3.0: Fix high latency during BTM roaming

While processing the WMA_ROAM_OFFLOAD_SYNCH_IND event, The
driver takes nearly 150 to 200 msec time to just write fatal,
error and info messages to the kmsg log buffer. Also to get
tx power supplicant runs another thread while roaming. These
cause more latency(300ms) to send WMA_ROAM_OFFLOAD_SYNCH_CNF
message to fw. To decrease roam latency, the driver should
write the only necessary error message to kmsg buffer.

The fix is to change irrelevant fatal, error and info message
type to debug add a check in __wlan_hdd_cfg80211_get_txpower
to reject the request to get Tx power while roaming in progress
otherwise driver will process this and will increase the roaming
latency.
