-GetComponentByName returns an allocated string, so let's free that if we
-fail somewhere.

-Subject: [PATCH] xkb: proof GetCountedString against request length attacks
-
-GetCountedString did a check for the whole string to be within the
-request buffer but not for the initial 2 bytes that contain the length
-field. A swapped client could send a malformed request to trigger a
-swaps() on those bytes, writing into random memory.
