sif: sqflush: Fix wrong casting in the calculation of CQ full

Orabug: 24735772

The CQ full is calculated via last posted seq number (last_seq)
minus the last completion seq number (head_seq). Both last_seq
and head_seq are defined as u16. However, in the calculation to
verify that the CQ is not full, a wrong casting is performed.
This causes a false negative of CQ full in the wrapped case.
