net/bnxt: set flow error when free filter not available

[ upstream commit 94df795 ]

In bnxt_flow_validate(), when bnxt_get_unused_filter() fails due to
no filter resources available, driver is not setting flow error using
"rte_flow_error_set".

Also, fixed the error code.

Fixes: 5ef3b79 ("net/bnxt: support flow filter ops")
