Modified Files:
        src/sys/miscfs/specfs: spec_vnops.c

Log Message:
Put workaround fix for LOCKDEBUG panic mentioned in PR kern/41078:
 Don't try to load a driver module if the driver is already exist but just
 not attached. [bc]dev_open() could return ENXIO even if the driver exists.

XXX: Maybe this should be handled by helper functions for
XXX: module_autoload() calls on demand.
