Sergio Lopez 019288bf13 hw/char/serial: Only retry if qemu_chr_fe_write returns 0 ... Only retry on serial_xmit if qemu_chr_fe_write returns 0, as this is the only recoverable error. Retrying with any other scenario, in addition to being a waste of CPU cycles, can compromise the Guest stability if by the vCPU issuing the write and the main loop thread are, by chance or explicit pinning, running on the same pCPU.
