qcacld-3.0: Fix LFR2 roam on same channel fail

When LFR2 roaming on same channel, after pre-auth resp received,
A new PE session is created, currentOperChannel is 0 before
lim_fill_ft_session, not same as currentOperChannel of original
session, so lim_is_in_mcc return true, pre-auth auth result is
not sent to SME/CSR for lim_ft_process_pre_auth_result isn't
called in lim_handle_ft_pre_auth_rsp
