net/mlx5e: Fix missing reset of SW metadata in Striding RQ reset

[ Upstream commit 39369fd536d485a99a59d8e357c0d4d3ce19a3b8 ]

When resetting the RQ (moving RQ state from RST to RDY), the driver
resets the WQ's SW metadata.
In striding RQ mode, we maintain a field that reflects the actual
expected WQ head (including in progress WQEs posted to the ICOSQ).
It was mistakenly not reset together with the WQ. Fix this here.
