Commit b673eab4e2 "multifd: Make multifd_load_setup() get an Error
parameter" changed migration_incoming_setup() to take an Error **
argument, and adjusted the callers accordingly. It neglected to
change adjust multifd_load_setup(): it still exit()s on error. Clean
that up.
The error now gets propagated up two call chains: via
migration_fd_process_incoming() to rdma_accept_incoming_migration(),
and via migration_ioc_process_incoming() to
migration_channel_process_incoming(). Both chain ends report the
error with error_report_err(), but otherwise ignore it. Behavioral
change: we no longer exit() on this error.
This is consistent with how we handle other errors here, e.g. from
multifd_recv_new_channel() via migration_ioc_process_incoming() to
migration_channel_process_incoming(). Whether it's consistently right
or consistently wrong I can't tell.
Also clean up the return value from the unusual 0 on success, 1 on
error to the more common true on success, false on error.
