Jiri Slaby (SUSE) ebee41c849 tty: tty_buffer: invert conditions in __tty_buffer_request_room()
We are used to handle "bad" states in the 'if's in the kernel. Refactor
(invert the two conditions in) __tty_buffer_request_room(), so that the
code returns from the fast paths immediately instead of postponing to
the heavy end of the function.
