checkpatch: fix false errors due to macro concatenation

The macro concatenation (##) sequence can cause false errors when checking
macro's.  Checkpatch doesn't currently know about the operator.

For example this line,

+ 	entry = (struct ftrace_raw_##call *)raw_data;                   \

is correct but it produces the following error,

ERROR: need consistent spacing around '*' (ctx:WxB)
+       entry = (struct ftrace_raw_##call *)raw_data;\
                                          ^

The line above doesn't have any spacing problems, and if you remove the
macro concatenation sequence checkpatch doesn't give any errors.

Extend identifier handling to include ## concatenation within the
definition of an identifier.
