staging: wilc1000: remove function pointer wlan_add_mgmt_to_tx_que

This patch removes function pointer wlan_add_mgmt_to_tx_que and just call
the function wilc_wlan_txq_add_mgmt_pkt.
Remove structure wilc_wlan_oup_t also because no members in it. Since
wilc_wlan_oup_t is deleted, it's variable, function parameters and related
codes are also deleted.
- deleted variables

- modified functions

wilc_wlan_init
