When building with CONFIG_KERNEL_DYNAMIC_DEBUG=y enabled, the build
fails with following error:

 <command-line>:0:37: error: redeclaration of enumerator 'IEEE80211_HW_REPORTS_TX_ACK_STATUS'
 <command-line>:0:37: note: in definition of macro 'IEEE80211_HW_TX_STATUS_NO_AMPDU_LEN'

   IEEE80211_HW_REPORTS_TX_ACK_STATUS,
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This is caused by failing check-cc-enum build check due to the following
compile error:

 ./include/linux/dynamic_debug.h:77:14: error: 'KBUILD_MODNAME' undeclared (first use in this function); did you mean 'KERN_NODENAME'?
    .modname = KBUILD_MODNAME,   \

So this patch adds missing KBUILD_MODNAME variable to
CHECK_CC_ENUM_FLAGS in order to make check-cc-enum build check compile
again.
