char: change qemu_chr_fe_add_watch to return unsigned
g_source_attach can return any value between 1 and UINT_MAX if you let
QEMU run long enough. However, qemu_chr_fe_add_watch can also return
a negative errno value when the device is disconnected or does not
support chr_add_watch. Change it to return zero to avoid overloading
these values.
Fix the cadence_uart which asserts in this case (easily obtained with
"-serial pty").
