[ Upstream commit 761156ff573d1002983416e4fd1fe8d3489c4bd8 ]
The length of wmi tlv command for management tx send is calculated incorrectly in case of protected management frames as there is addition of IEEE80211_CCMP_MIC_LEN twice. This leads to improper behaviour of firmware as the wmi tlv mgmt tx send command for protected mgmt frames is formed wrongly.
Fix the length calculation of wmi tlv command for mgmt tx send in case of protected management frames by adding the IEEE80211_CCMP_MIC_LEN only once.
Tested HW: WCN3990 Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1
