[Cluster-devel] [PATCH dlm/next 2/2] fs: dlm: handle -EINVAL as log_error()

If the user generates a -EINVAL it's probably because the user using DLM
wrong. To give the user notice about that wrong behaviour we should
always print -EINVAL errors on the proper loglevel. In case of other
errors like -EBUSY it will be still printed on debug loglevel as the
current API handles it as "retry again".
