[media] coda: fix double call to debugfs_remove

Browse Source 
In coda_free_aux_buf() call debugfs_remove only if buffer entry
is valid (and therfore dentry is valid), double protect by
invalidating dentry value.

Fixes erroneous prematurely dealloc of debugfs caused by
incorrect reference count incrementing.
