    common: Avoid conflict with __bitwise macro from linux/types.h
    
    Undefine the __bitwise macro before defining it to avoid conflicts
    with the one from linux/types.h; the same is done some lines above
    when __CHECKER__ is defined. Fixes the following warning:
    
      In file included from ../src/l2_packet/l2_packet_linux.c:15:0:
      hostap/src/utils/common.h:438:0: warning: "__bitwise" redefined
       #define __bitwise

      /usr/include/linux/types.h:21:0: note: this is the location of the previous definition
       #define __bitwise __bitwise__
