USB: serial: return errors from break handling

This series starts returning errors from break handling and also uses that mechanism to report to user space when break signalling is not supported (e.g. when device or driver support is missing). Note that the tty layer currently returns early but without reporting errors when a tty driver does not support break signalling. The intent expressed in commit 9e98966c7bb9 ("tty: rework break handling") from 2008 appears to be to allow missing support to be reported to user space however.
