IB/qib: Fix txselect regression
commit 2fadd83184d58701f1116ca578465b5a75f9417c upstream. Commit 7fac33014f54("IB/qib: checkpatch fixes") was overzealous in removing a simple_strtoul for a parse routine, setup_txselect(). That routine is required to handle a multi-value string. Unwind that aspect of the fix.
