struct-attr: prepare to handle attributes at the end of struct definitions (2)

Type attributes for struct can be placed either just after the
keyword 'struct' or after the '}' ending its definition but this
later case is currently ignored.

Prepare the handling of this by restructuring the code handling
struct specifiers, namely inverting the condition so that the
function can return early to make next patch's job easier.
