kernel-doc: strip attributes even if they have an argument
An inline function can have an attribute, as in include/linux/log2.h,
and kernel-doc handles this already for simple cases. However,
some attributes have arguments (e.g. the "target" attribute).
Handle those too.
Furthermore, attributes could be at the beginning of a function
declaration, before the return type. To correctly handle this case,
you need to strip spaces after the attributes; otherwise, dump_function
is left confused.
