libhns: Fix missing fields for SRQ WC

[ Upstream commit 65a7ce9 ]

The sl and src_qpn fields in recv-WC are not filled when the QP is UD
and has an SRQ. Here fix it.

In addition, UD QP does not support RQ INLINE and CQE INLINE features.
Reorder the related if-else statements to reduce the number of
conditional checks in IO path.
