kernel-doc: fix declaration type determination
Make declaration type determination more robust. When scripts/kernel-doc is deciding if some kernel-doc notation contains an enum, a struct, a union, a typedef, or a function, it does a pattern match on the beginning of the string, looking for a match with one of "struct", "union", "enum", or "typedef", and otherwise defaults to a function declaration type. However, if a function or a function-like macro has a name that begins with "struct" (e.g., struct_size()), then kernel-doc incorrectly decides that this is a struct declaration. Fix this by looking for the declaration type keywords having an ending word boundary (\b), so that "struct_size" will not match a struct declaration. I compared lots of html before/after output from core-api, driver-api, and networking. There were no differences in any of the files that I checked.
