isdn: prevent NULL ptr Oops in capi_cmsg2str()
The dereferencing of the private pointer cmsg->m in capi_cmsg2str() may
cause an Oops in case of an error, which is particularly inconvenient
as that function is typically used to format an error message. Add a
NULL pointer check to avoid this.
Impact: error handling improvement
