staging: Comedi: comedi_fops: Fixed the return error code 



This patch fixes the checkpatch.pl warning:

WARNING: ENOSYS means 'invalid syscall nr' and nothing else

try_module_get fails when the reference count of the module is not
allowed to be incremented ,and hence -ENXIO is returned indicating
no device or address.

[IA - combined two of santhosh's changes to the error return value!]
