IB/qib: Remove s_lock around header validation
Review of qib_ruc_check_hdr() shows that the s_lock is not required in
the normal case. The r_lock is held in all cases, and protects the qp
fields that are read.
The s_lock will be needed to around the call to qib_migrate_qp() to
insure that the send engine sees a consistent set of fields.
