[PATCH] staging: rtl8192u/ieee80211: Fix sparse ieee80211_debug_init/_exit not declared warning

[Jeremiah Mahler]

A sparse warning is generated about 'ieee80211_debug_init' and
'ieee80211_debug_exit' not being declared.

  drivers/staging/rtl8192u/ieee80211/ieee80211_module.c:275:12: warning:
  symbol 'ieee80211_debug_init' was not declared. Should it be static?
  drivers/staging/rtl8192u/ieee80211/ieee80211_module.c:297:13: warning:
  symbol 'ieee80211_debug_exit' was not declared. Should it be static?

These functions are used outside of this file so using static will not
work.  Fix the warning by declaring the functions in the header file,
ieee80211.h
