misc: trivial: Remove undesired double space from struct definition

When one is too lazy to use an LSP to conduct look-ups on struct
definitions, one might use the ever useful `struct <name> {` search
string.  However this doesn't work with `struct miscdevice  {` because
of a stray double space.  Assuming that this wasn't intentional, let's
simply remove it.
