35b1561e3ec56fc3cae283d1b00053be6445a2db migration/rdma: Silence qemu_rdma_connect()
Functions that use an Error **errp parameter to return errors should
not also report them to the user, because reporting is the caller's
job. When the caller does, the error is reported twice. When it
doesn't (because it recovered from the error), there is no error to
report, i.e. the report is bogus.
qemu_rdma_connect() violates this principle: it calls error_report()
and perror(). I elected not to investigate how callers handle the
error, i.e. precise impact is not known.
Clean this up: replace perror() by changing error_setg() to
error_setg_errno(), and drop error_report(). I believe the callers'
error reports suffice then. If they don't, we need to convert to
Error instead.
Bonus: resolves a FIXME about problematic use of errno.
