IB/{hfi1,qib}: Cleanup open coded sge sizing
Sge sizing is done in several places using an open coded method.
This can cause maintenance issues. The open coded method is
encapsulated in a helper routine. The helper was introduced with
commit:
1198fcea8a78 ("IB/hfi1, rdmavt: Move SGE state helper routines into
rdmavt")
Update all call sites that have the open coded path with the helper
routine.
