wifi: radiotap: fix kernel-doc notation warnings

Fix a typo (82011 -> 80211) to prevent a kernel-doc warning.
Add one missing function parameter description to prevent a
kernel-doc warning.

ieee80211_radiotap.h:52: warning: expecting prototype for struct ieee82011_radiotap_header. Prototype was for struct ieee80211_radiotap_header instead
ieee80211_radiotap.h:581: warning: Function parameter or member 'data' not described in 'ieee80211_get_radiotap_len'
