Subject: fabrics: fix infinite loop on invalid parameters
Git-commit: 81f54310e74f0a82c25a6f8a21316c30f1801299
References: bsc#1200644

When parsing the discovery entries results in invalid parameters
for a given connection we'll enter an infinite loop as the -EINVAL
error code is always assumed to indicate a wrong 'disable_sqflow'
setting.
