staging: wilc1000: refactor host_int_parse_assoc_resp_info() to remove unused code

Remove 'connect_resp_info' structure as most of its elements are not used.

Modified wilc_parse_assoc_resp_info() to directly parse and fill value
in connect_info structure variable. Remove use of 'assoc_resp_len' variable.
get_assoc_resp_cap_info() & get_asoc_id() functions are remove as its
not used anymore.
