staging: wilc1000: remove function pointer wlan_handle_tx_que

This patch removes function pointer wlan_handle_tx_que and just call
the function wilc_wlan_handle_txq. Remove static from the function also.
There is one function call wlan_handle_tx_que which does not have an argument
and return value. So put txq_count as argument and ret for return value.
