checkpatch: change externals to globals

Make error message say 'ERROR: do not initialise globals to 0 or NULL'
rather than 'ERROR: do not initialise externals to 0 or NULL'.  Makes more
sense in the context since there is an extern keyword in C and that is a
global declaration within the scope of the current file.
