Nicholas Piggin 7f2bf7840b tty: hvc: hvc_write() fix break condition ...

Commit 550ddadcc758 ("tty: hvc: hvc_write() may sleep") broke the
termination condition in case the driver stops accepting characters.
This can result in unnecessary polling of the busy driver.

Restore it by testing the hvc_push return code.
