We can call qemu_chr_fe_set_handlers() to add/remove fd been watched
in 'context' which can be either default main context or other explicit
context. But the original logic is not correct, we didn't remove
the right fd because we call g_main_context_find_source_by_id(NULL, tag)
which always try to find the Gsource from default context.
Fix it by passing the right context to g_main_context_find_source_by_id().

When a serial port writes data to a pty that's disconnected, drop the
data and return the length dropped. This avoids triggering pointless
retries in callers like the 16550A serial_xmit(), and causes
qemu_chr_fe_write() to write all data to the log file, rather than
logging only while a pty client like virsh console happens to be
connected.
