WNM: Remove unused code from BSS TM Req generation 

The url argument to ieee802_11_send_bss_trans_mgmt_request() was
hardcoded to NULL in the only caller, so this code cannot be reached.
wnm_send_bss_tm_req() construct the same frame with more generic
parameters, including option for including the URL, so
ieee802_11_send_bss_trans_mgmt_request() can be simplified.
