Subject: [PATCH 53/62] net/mlx5: Check for SQ and not RQ state when modifying hairpin SQ

[ Upstream commit 6b359d5550a1ae7a1269c9dc1dd73dfdc4d6fe58 ]

When modifying hairpin SQ, instead of checking if the next state equals
to MLX5_SQC_STATE_RDY, we compare it against the MLX5_RQC_STATE_RDY enum
value.

The code worked since both of MLX5_RQC_STATE_RDY and MLX5_SQC_STATE_RDY
have the same value today.

This patch fixes this issue.
