Fix inner attribute parsing
parse_inner_attribute tried to skip the right square token twice. This caused odd error
messages in case there were multiple inner attributes. This bug masked another bug in
parse_attr_input where when the (optional) attr input was an assignment to a literal
the parser failed to skip the literal.
The existing top_attr.rs testcase relied on the two bugs cancelling each other out.
Add a new testcase inner_attributes.rs for the first bug.
