[PATCH] fix drivers/char/misc.c module autoloading breakage

drivers/char/misc.c was changed to use the common list macros instead of
its own list code.  The first open does load the module and increment
its use count, but a bug causes a failure to be reported anyway.  This
causes an error return to user-space where there is none, and makes the
module non-unloadable.

Fixed like this.
