[PATCH rdma-core 1/2] cxgb4: fix chipversion initialization

[Potnuri Bharat Teja <bharat@xxxxxxxxxxx>]

With Commit `0c3cecfe04d5a`, device and vendor members of structure
verbs_match_ent are left unintialised. This causes c4iw_alloc_context()
failure due to incorrect chipversion.
This patch reorders the code to fetch chipversion from ib device attributes.
