qcacld-3.0: Fix to set ptk_installed to true in 11R roaming

qcacld-2.0 to qcacld-3.0 propagation

PTK exchange and install happens during preauthentication if key_mgmt is
FT-PSK. STA TL state moves to authenticated only if ptk_installed is true.
Currently ptk_installed is false after roaming due to which STA TL state
does not move to authenticated state and also does not enter BMPS.

To fix this issue, set ptk_installed to true in case of 11R roaming
